Yoga and its Relevance in the Modern Times

2.1 Core concepts

• Yoga is a science of living that works on physical, mental, emotional, social and spiritual levels of human beings; it is an art and science for healthy living (NCERT §Intro, p. 210).
• The word yoga is derived from the Sanskrit root yuj meaning "to join, to yoke, and to unite"; it is an ancient system of self-development and natural evolution of human beings (NCERT §Intro, p. 210).
• According to the Upanishads, yoga is a higher state of consciousness and a process to ease the mind and manifest wisdom (NCERT §Intro, p. 210).
• History: Yoga finds place in the Indus Valley Civilisation (2000 B.C.) where stone seals depict yogic practice; it is referred to in all four Vedas — Rigveda, Yajurveda, Samaveda, Atharvaveda (NCERT §History, p. 211).
• Moksha is the ultimate goal of yoga (explained in the Upanishads); Buddha's Arya Asthangic Marga and Jainism's five great vows are the two pillars of the yoga tradition; Ramayana, Mahabharata and especially the Bhagavad Gita (a classical treatise on yoga) discuss it (NCERT §History, p. 211).
• Maharishi Patanjali codified yoga around the second century B.C. and gave the concept of the eight limbs of yoga called Ashtang Yoga (NCERT §History, p. 211).
• Nath culture played an important role in developing the Hatha Yoga tradition; key scriptures of Hatha Yoga are Hatha Yoga Pradeepika, Gheranda Samhita, Hatha Ratnavali, Shiva Samhita, Siddha Siddhanta Paddhati (NCERT §History, p. 211).
• Schools of Yoga (four):
• Karma Yoga (Path of Action) — emphasises action as duty; three attributes: Karma as duty, Karma Sukaushalam (skilled efficient action), Nishkama Karma (action free from personal motives / expectations of result) (NCERT §Schools, pp. 211–212).
• Jnana Yoga (Path of Knowledge) — overcomes avidya (ignorance) through viveka (discriminating knowledge); three stages — shravan (adequate hearing), manana (constant remembrance), nidhidhyasana (contemplation/meditation) (NCERT §Schools, p. 212).
• Raja Yoga (Path of Psychic Control) — controls chittavrittis through abhyasa (continuous practice) and vairagya (detachment); based on Ashtanga Yoga (eight-limbed) of Patanjali (NCERT §Schools, pp. 212–213).
• Bhakti Yoga (Path of Devotion) — nine forms: Shravan, Kirtan, Smaran, Padsevan, Archana, Vandana, Dasya, Sakhya, Atmanivedan (NCERT §Schools, p. 213).
• Guidelines for practice: Before — Shauch (cleanliness), empty stomach, even surface, mattress/durry, cotton clothes, never in exhaustion/illness (NCERT §Guidelines, p. 213). During — begin with prayer, breathe through nostrils unless instructed otherwise, regular practice, consult doctor for chronic/cardiac/pregnancy/menstruation cases. After — bath and light food only after 15–30 minutes, end with Shavasana, meditation and Shanti Path (NCERT §Guidelines, p. 214).
• Wellness through Yoga: Mechanisms include Shodhana Kriyas (cleanse toxins), yogic diet (antioxidant enhancement), Yogasana (postural steadiness), Pranayama (autonomic respiratory control), Dharana (focus), Dhyana (contemplation) (NCERT §Yogic Principles, p. 215).
• Shodhana Kriyas — Neti: A Hathayogic Kriya for cleaning the nasal passage; pre-requisite for Pranayama. Two types — Jala Neti (water; performed in Kagasana, lukewarm salted water before sunrise) and Sutra Neti (thread; insert one hand-span thread through nose, draw out through mouth; do not attempt unless Jala Neti is perfected) (NCERT §Yoga for Wellness, pp. 215–217).
• Kapalbhati: Kapala = skull/head, Bhati = to shine — rejuvenates skull and mental functions; deep inhalation through both nostrils, forceful exhalation by abdominal contraction; "bellows-type" breathing 30–40 strokes per round (start from 10); avoid in high BP, heart disease, gastric ulcers (NCERT §Kapalbhati, pp. 217–218).
• Agnisara (also Vahnisara) — Vahni/Agni = fire, Sara = essence; the essence of fire resides in navel region. Stand erect, bend knees at 60°, exhale completely, contract and expand abdominal muscles rapidly while retaining breath outside (NCERT §Agnisara, p. 218).
• Surya Namaskara: Sun salutation — set of seven asanas in twelve steps, performed every morning with breathing technique. Steps: 1. Namaskarasana, 2. Hastottanasana, 3. Padhastasana, 4. Ashwasanchalanasana, 5. Parvatasana, 6. Ashtanga Namaskarasana, 7. Bhujangasana, 8. Parvatasana, 9. Ashwasanchalanasana, 10. Padhastasana, 11. Hastottanasana, 12. Namaskarasana (NCERT §Surya Namaskara, pp. 219–221).
• Yogasanas covered: Tadasana (palm-tree posture), Vrikshasana (tree), Padahastasana (palms-to-feet), Ardha Chakrasana (half-wheel), Trikonasana (three-angle), Parshvakonasana (lateral angle), Padmasana (lotus — knees should touch ground), Vajrasana (the only posture that can be practised immediately after meal), Bhadrasana, Ushtrasana (camel), Shashankasana (rabbit), Uttanamandukasana (upright frog — head held by elbows), Paschimottanasana (back-stretch), Suptavajrasana, Vakrasana (twist), Ardhamatsyendrasana (modified — named after yogi Matsyendranatha), Gomukhasana (cow's face), Makrasana (crocodile — relaxation), Bhujangasana (cobra), Shalabhasana (locust — stimulates parasympathetic NS), Pawanmuktasana (wind-releasing), Setubandhasana (bridge), Viparitkarani (inverted), Shavasana (corpse — final relaxation) (NCERT §Yogasana, pp. 222–242).
• Pranayama: Prana = vital force, Ayama = restraint; three phases — Puraka (inhalation), Kumbhaka (retention; performed with Mulabandha, Uddiyanabandha, Jalandharbandha), Rechaka (exhalation — duration supposed to be double of puraka) (NCERT §Pranayama, pp. 242–243).
• Yogic Deep Breathing combines three types: Abdominal, Thoracic, Clavicular. Nadishodhana Pranayama (also anuloma-viloma) purifies nadis by alternate-nostril breathing with nasagran mudra on right hand and jnana mudra on left (NCERT §Pranayama, pp. 243–245). Ujjayi Pranayama — sit in Padmasana/Siddhasana, partial closing of glottis produces a peculiar sound on inhalation; removes heat and phlegm (NCERT §Ujjayi, pp. 245–246).
• Bandhas: Means to hold or lock; introduced during mudra and pranayama. Jalandhara Bandha — chin to chest while retaining breath (improves thyroid function); Uddiyana Bandha — exhale fully, pull abdominal muscles up and inside towards spine (improves blood circulation and tones abdominal organs) (NCERT §Bandhas, pp. 246–247).
• Dhyana: Part of Astanga yoga; reached after shatkarma, asana, pranayama; focused on a single point — a mantra or an object; activates parasympathetic nervous system; controls BP, normalises heart rate, reduces anxiety (NCERT §Dhyana, p. 248).

2.4 Common confusions / NTA trap points

• Karma Sukaushalam (skilled action / efficiency) vs Nishkama Karma (action without expectation of results) — both fall under Karma Yoga but mean different things (p. 212).
• The eight limbs are part of Raja Yoga — which is based on Patanjali's Ashtanga Yoga; do not confuse with Buddha's Arya Asthangic Marga (Eightfold Path), which is one of the two pillars of yoga tradition (p. 211).
• The duration of Rechaka is supposed to be double that of Puraka (not equal, not half) — frequent trap in pranayama questions (p. 243).
• Vajrasana is the only asana that can be done immediately after meals; Padmasana, Sukhasana etc. cannot (p. 227).
• Jala Neti uses lukewarm salted water before sunrise, breathing must be through the mouth during the practice — NTA often flips these (p. 216).
• Sutra Neti must not be attempted unless Jala Neti is perfected (p. 217).
• Bhakti Yoga has nine forms (Shravan, Kirtan, Smaran, Padsevan, Archana, Vandana, Dasya, Sakhya, Atmanivedan) — not seven.
• Jnana Yoga stages = Shravan → Manana → Nidhidhyasana (hearing, remembrance, contemplation). NTA may rearrange the order.
• Patanjali codified Ashtang Yoga in the 2nd century B.C. — not 2nd century A.D.
• Kapalbhati avoidance: high BP, heart disease, gastric ulcers — NTA might list "obesity" as a contraindication, which is wrong (it's a benefit).
• The four Vedas referencing yoga are Rig, Yajur, Sama, Atharva — all four. Sub-listing only three is a trap.
• Surya Namaskara = 12 steps built from 7 asanas (some repeat, e.g., Hastottanasana appears at steps 2 and 11).
• Bandhas: Jalandhara (chin to chest), Uddiyana (abdomen in & up), Mula (perineum lock). Often mis-assigned.
• Pranayama = Prana + Ayama (vital force + restraint); Ayama is NOT "control" alone — it includes both extension and restraint.

2.5 Key concepts table — schools, kriyas, asanas, pranayamas

2.6 Extended discussion — historical layers, scientific basis and CUET strategy

A layered chronology runs through this topic and CUET regularly tests it. Layer 1 — pre-Vedic: Indus Valley seals (2000 BC) showing meditative postures. Layer 2 — Vedic: Yoga appears in all four Vedas (Rig, Yajur, Sama, Atharva). Layer 3 — Upanishadic: Moksha defined as the ultimate goal. Layer 4 — Sramana: Buddha's Arya Asthangic Marga (Eightfold Path) and Jainism's five great vows treated as twin pillars of the yoga tradition. Layer 5 — Epic: Ramayana, Mahabharata, and the Bhagavad Gita as a classical treatise on yoga. Layer 6 — Classical: Patanjali codifying the eight limbs of Ashtang Yoga around the second century BC. Layer 7 — Nath / Hatha tradition: scriptures like Hatha Yoga Pradeepika, Gheranda Samhita, Hatha Ratnavali, Shiva Samhita, Siddha Siddhanta Paddhati. Layer 8 — Modern: Vivekananda, Aurobindo, Ramana Maharishi popularising yoga in the 19th–20th century. Most CUET items pick a single layer and ask either a who–when recall or a which-text identification.

The four schools (Karma, Jnana, Raja, Bhakti) provide a second exam-favourite skeleton. The trick is to lock each school to its central operative concept: Karma = duty + Nishkama; Jnana = Viveka against Avidya; Raja = control of Chittavrittis via Abhyasa + Vairagya; Bhakti = devotional surrender in nine forms. The Bhakti nine — Shravan, Kirtan, Smaran, Padsevan, Archana, Vandana, Dasya, Sakhya, Atmanivedan — are a stand-alone NTA mini-cluster.

The operative chapter spine runs Shodhana Kriyas → Surya Namaskara → Yogasanas → Pranayama → Bandhas → Dhyana. Each layer has a distinct physiological signature that examiners exploit. Shodhana Kriyas (Neti, Kapalbhati, Agnisara) clean nasal/pharyngeal/abdominal passages and prepare the body for Pranayama. Surya Namaskara integrates 7 asanas into 12 steps with synchronised breathing — equivalent to a complete cardio-strength-flexibility routine in 5 minutes. Yogasanas develop postural endurance and target specific organ systems (Shalabhasana — parasympathetic; Vajrasana — digestion; Padmasana — meditation base). Pranayama controls autonomic respiration through the three phases Puraka–Kumbhaka–Rechaka, with Rechaka twice the duration of Puraka. Bandhas (Jalandhara, Uddiyana, Mula) lock prana inside during Kumbhaka. Dhyana culminates the journey with single-point focus, activating the parasympathetic nervous system to lower blood pressure, normalise heart rate and reduce anxiety.

For CUET, the figure-based identification questions are increasingly common — a posture image with four asana names as options. The minimum visual vocabulary required is Tadasana (palm-tree), Vrikshasana (tree, single-leg balance), Trikonasana (triangle, lateral bend), Padmasana (lotus, cross-legged), Vajrasana (diamond, kneeling on heels), Bhujangasana (cobra, prone backbend), Shalabhasana (locust, prone legs up), Pawanmuktasana (wind-relieving, knees to chest), Setubandhasana (bridge), Shavasana (corpse, supine relaxation). Pair the image with one signature benefit and you can answer almost any CUET item from this chapter.
