Yoga Practice and Alignment

Yoga as practiced in most of the modern world descends through Tirumalai Krishnamacharya (1888–1989) of Mysore, and branches through his three most famous students — B.K.S. Iyengar, Pattabhi Jois, and T.K.V. Desikachar — into distinct schools. This skill centers the Iyengar voice because the chair of the mind-body department is B.K.S. Iyengar, and the Iyengar method is where alignment and prop-based progression are most explicit. The skill also gives routing-level knowledge of the other lineages so an agent is not trapped inside a single school when the user belongs to another one.

Agent affinity: iyengar (asana alignment, props, sequencing, teacher-level detail), thich-nhat-hanh (mindful movement framing), kabat-zinn (MBSR mindful movement, secular framing for clinical users)

Wings covered: yoga (primary). Lineage roots: Patanjali's Yoga Sutras as eight-limb philosophical scaffold; Hatha Yoga Pradipika for the classical asana frame; Krishnamacharya for the modern transmission; Iyengar's Light on Yoga and Light on Pranayama for the alignment-and-prop method; Pattabhi Jois for Ashtanga; Desikachar for Viniyoga; the restorative tradition through Judith Hanson Lasater; Yin through Paul Grilley; chair yoga through Lakshmi Voelker.

1. Lineage map — who teaches what, and why it matters for routing

An honest yoga skill has to admit that "yoga" means many different things. The same asana name is taught with different alignment cues in different schools, and a teacher trained in one lineage may actively disagree with another.

• Iyengar yoga (B.K.S. Iyengar, Pune, India). Precision, prop use, long holds, staged progression. Poses are taught as craft — alignment is spelled out in fine detail, and props are used to give every body access to the shape. The reference text is Light on Yoga (1966). Teacher training is long and certification is lineage-gated.
• Ashtanga vinyasa (Pattabhi Jois, Mysore, India). A fixed series of postures linked by vinyasa, taught Mysore-style (self-practice under a teacher's eye). Fast, athletic, ujjayi-breath-through-the-whole-practice. The primary, intermediate, and advanced series are prescribed.
• Viniyoga (T.K.V. Desikachar, Chennai, India). Practice adapted to the individual. Sequences are designed for the student in front of you, not for a fixed series. Breath is central and often precedes posture.
• Hatha yoga (broad umbrella). Anything that trains the physical body (asana and pranayama) to prepare for meditation. Most non-lineage "yoga class at a gym" is generic Hatha.
• Restorative yoga (Judith Hanson Lasater, from the Iyengar lineage). Fully supported postures held 5–20 minutes. Deeply parasympathetic. Useful for recovery, stress, and injury.
• Yin yoga (Paul Grilley, building on Paulie Zink's Taoist yoga). Long passive holds (3–5 minutes) targeting fascia and connective tissue. Not the same as restorative.
• Chair yoga (Lakshmi Voelker and others). Yoga adapted for the chair. Appropriate for older adults, mobility-limited practitioners, workplace practice, and rehab.
• Bikram / hot yoga (Bikram Choudhury). A fixed 26-posture sequence in a heated room. This lineage has a well-documented history of abuse by its founder; mention it for completeness and for context about a user's history, but do not recommend new practice in it.

A routing agent must ask or infer which lineage the user is already inside before prescribing. Giving an Ashtanga student Iyengar-length holds, or giving an Iyengar student Ashtanga-speed vinyasa, is a category error.

2. Asana families — the organizing structure

The Iyengar school groups asanas into families because the alignment principles within a family transfer across poses. A routing agent that understands the families can generate useful home practice even without memorizing every pose.

2.1 Standing poses

Tadasana (mountain), utthita trikonasana (extended triangle), virabhadrasana I, II, III (warrior 1, 2, 3), parsvakonasana (extended side angle), parsvottanasana (intense side stretch), utkatasana (chair), vrksasana (tree). The standing poses are where Iyengar students live for their first year. They train the legs and the pelvis to support everything else.

Alignment principles for the standing-pose family:

• The outer edges of both feet are parallel to the mat edge, or turned in the prescribed way for the pose. The weight is distributed to four corners of each foot.
• The kneecaps track over the second and third toes. A knee that collapses inward is a routing flag — stop and correct before progressing.
• The quadriceps lift the kneecaps. This locks the knee safely.
• The tailbone lengthens down. The lower ribs draw back toward the spine.
• The crown of the head lifts away from the pelvis.

2.2 Seated poses

Dandasana (staff), paschimottanasana (seated forward fold), janu sirsasana (head-to-knee), baddha konasana (bound angle), upavistha konasana (wide seated angle), virasana (hero), sukhasana (easy). Seated poses are where hamstring and hip-joint tightness produces the most misalignment. Use props aggressively — a folded blanket under the sit-bones, a strap around the feet, a block between the knees.

2.3 Forward folds

Uttanasana (standing forward fold), prasarita padottanasana (wide-legged forward fold), paschimottanasana (seated). The Iyengar cue "fold from the hip joint, not the waist" is the key. Fold from the hip joint with a flat back as far as possible, then allow any rounding. Rounding from the waist is how backs get hurt.

2.4 Backbends

Urdhva mukha svanasana (upward-facing dog), bhujangasana (cobra), setu bandha sarvangasana (bridge), urdhva dhanurasana (wheel), ustrasana (camel). The backbend family is high-reward and high-risk. Key cue: lengthen the spine before arching it. The lumbar is where most backbend injuries happen; protect it by engaging the legs and drawing the pubis forward.

2.5 Twists

Ardha matsyendrasana, marichyasana, parivrtta trikonasana, parivrtta parsvakonasana, bharadvajasana. Twists are sequenced before backbends in Iyengar sequences because they release the spine. Key cue: lengthen the spine on the inhale, twist on the exhale. Never force a twist — the depth should come from the exhale.

2.6 Inversions

Salamba sirsasana (headstand), salamba sarvangasana (shoulderstand), halasana (plow), viparita karani (legs-up-wall). Inversions are the most famous Iyengar poses and the most safety-sensitive. Headstand and shoulderstand require dedicated preparation, usually a year or more of foundational work in the other families before they are introduced.

2.7 Arm balances

Bakasana (crow), chaturanga dandasana, pincha mayurasana (forearm balance), adho mukha vrksasana (handstand). Arm balances are a small family in the Iyengar method and a large one in Ashtanga. They come after the standing-pose foundation.

2.8 Recuperative / restorative

Savasana (corpse), supta baddha konasana (reclined bound angle), setu bandha sarvangasana with a bolster. Every full practice closes with savasana, minimum 5 minutes.

3. The prop toolbox

Iyengar's lasting contribution to world yoga is the prop. Props do not make a practice "easier" — they make the alignment accessible so the practitioner can feel the correct shape. Then the prop is gradually removed.

| Prop | Primary use | |---|---| | Block (cork or foam) | Raise the floor. Under the hand in triangle so the chest can open. Between the knees to train adduction. Under the sacrum in supported bridge. | | Strap | Extend the arms. Around the foot in supine hamstring stretch. Across the back in gomukhasana when the hands do not meet. Around the upper arms in headstand prep. | | Bolster | Support the spine and the breath. Lengthwise under the
