Siddhāsana

Classical Description

The Haṭha Yoga Pradīpikā (1.35-37) gives the most detailed description:

“Pressing the perineum firmly with the heel of one foot, place the other foot over the genitals. Then, fixing the chin on the chest, remain motionless with senses controlled, gazing at the point between the eyebrows. This is Siddhāsana, which opens the door to liberation.”

The text continues (1.38):

“Some call it Siddhāsana, others Vajrāsana, others Muktāsana, and others Guptāsana.”

Technique

1. Sit with legs extended
2. Bend the left leg and place the heel against the perineum (between the anus and genitals)
3. Bend the right leg and place the foot on the left ankle, with the heel at the base of the pubis
4. The toes of the right foot may be inserted between the thigh and calf of the left leg
5. Spine erect, hands in jñāna mudrā on the knees

Benefits According to the Texts

The HYP is emphatic (1.39-40):

“Of the 84 āsanas, Siddhāsana should always be practiced. It purifies the 72,000 nāḍīs.”

“What need is there for many āsanas when Siddhāsana has been mastered? When prāṇa is stilled through kumbhaka in this posture, absorption (unmani) arises naturally.”

Other benefits:

• Stimulates mūlādhāra chakra through heel pressure
• Channels apāna-vāyu upward
• Considered superior to Padmāsana for prolonged practice
• Leads to siddhi (perfection) — hence its name

Notes

The name Siddhāsana derives from siddha (perfect, adept). It is the posture of yogis who have attained perfection. The texts consider it the āsana par excellence for prāṇāyāma and meditation. It is generally more accessible than Padmāsana for most practitioners.
