📜 Scriptural References

Haṭha Yoga Pradīpikā (1.28–1.29)

Verse 28

prasārya pādau bhuvi dāṇḍarūpau … jānuparinyasta‑lalāṭadeśo vased idam paścimatānam āhuḥ

Stretch the legs on the ground like a staff; hold both big toes with the hands and place your forehead on the knees. This is called Paścimottānāsana.

Verse 29

pavanaṁ paścimavāhinaṁ karoti … udare kārśyam arogatāṃ ca puṁsām

Paścimottānāsana makes the vital air travel through the back ('śushumnā'), increases digestive fire, flattens the abdomen, and frees the practitioner from disease.

Gheraṇḍa Saṁhitā (2.24)

Spread the legs on the ground as stiff as a stick; hold the forehead on the knees and catch the toes with your hands. This is called Paścimottānāsana.

Śiva Saṁhitā (3.92–3.94)

Verse 92:
“Stretch both legs; hold the head and place it on knees. This is Ugrasana or Paschimottānāsana. Practiced daily, it induces prāṇa flow through the posterior channel and eliminates dullness.”
Verses 93–94: It grants vāyu-siddhi (control over vital air), destroys misery, and is reserved for those seeking siddhis. 

🧭 Step‑by‑Step Instructions

⚠️ Before you begin: If you have tight hamstrings, back pain, or are unable to sit upright without rounding your spine, sit on a firm folded blanket or cushion to elevate your hips slightly above your legs. This makes the pose safer and more accessible.

🪑 1. Sit Down with Your Legs Straight

• Sit on the floor with your legs stretched straight in front of you.
• Keep both legs together, touching each other from thighs to ankles.
• Make sure your toes point straight upward, not outward or sideways.
• Sit tall. Try to lengthen your spine upward, as if someone is gently pulling the crown of your head toward the sky.
• Keep your hands beside your hips, palms resting on the ground or thighs.

📏 2. Adjust Your Sitting Bones and Posture

• Use your hands to gently pull the flesh away from your buttocks so you can feel both sitting bones firmly in contact with the floor or cushion.
• This helps your pelvis tilt slightly forward — an important step to protect your back.
• Keep your chest open and shoulders relaxed, not hunched.

🙌 3. Inhale and Raise Your Arms Overhead

• Take a deep breath in (inhale slowly).
• As you inhale, lift both arms straight up over your head, keeping them close to your ears.
• Stretch your spine tall — feel the length from your sitting bones to your fingertips.
• Keep your arms parallel and your elbows straight.

🌬️ 4. Exhale and Begin to Bend Forward — From the Hips

• As you breathe out, start bending forward slowly — but don’t drop your head or hunch your upper back.
• Hinge forward from your hip joints, not your waist. Imagine the front of your belly reaching toward your thighs, not your head to your knees.
• Keep your spine long and straight as much as possible — like a flat tabletop.

🤲 5. Reach Toward Your Feet — Gently

• Let your hands reach as far forward as they naturally can. Aim for your:
  • Shins (beginners)
  • Ankles (if accessible)
  • Feet or toes (only if you can do so without force)
• If you can’t reach, that’s okay. Keep your arms extended forward, or rest your hands on your legs wherever they reach.
• DO NOT yank or pull on your feet or legs — the stretch should feel gentle and steady, not strained or painful.

🧘 6. Relax and Stay in the Pose

• Allow your head, neck, and shoulders to relax naturally once you’re in your maximum comfortable forward position.
• Stay here for 5 to 10 deep, slow breaths.
• With each exhalation, see if your body naturally softens forward a little more — but never push yourself deeper forcefully.
• Your belly should stay relaxed and, if possible, gently touch your thighs.

🌀 7. To Come Out of the Pose

• Inhale and slowly lift your torso upright, stacking each part of your spine gently back up — don’t jerk upward.
• Bring your arms back down to your sides and relax your shoulders.
• You may want to shake out your legs gently or sit with crossed legs for a few moments to release the stretch.

🧷 Important Beginner Tips:

• If your hamstrings are tight and you're rounding your back a lot, bend your knees slightly — this protects your spine.
• Never force your head to touch your knees. The goal is not to fold as deep as possible, but to elongate the spine and stretch safely.
• If your back begins to hurt or strain, come up slowly and reset. Use props like a strap around the feet if needed.

⚠️ Contraindications & Cautions

• Avoid with slipped disc, severe sciatica, lower back injury, hernia, or pregnancy.
• Keep knees softly bent or use props if hamstrings are tight.
• Be gentle during first trimester; pressure on abdomen can be contraindicated.

🔄 Preparatory Practices

• Dandāsana – base alignment
• Marjārī–Vyāyānī (Cat–Cow) – mobilizes spine
• Supta Paschimottānāsana (Reclining variation) – passive stretch
• Ardha Paścimottānāsana (1-leg forward bend) – accessible variation
