The Siddhâsana
Press firmly the heel of the left foot against the perineum, and the right heel above the male organ. With the chin pressing on the chest, one should sit calmly, having restrained the senses, and gaze steadily the space between the eyebrows. This is called the Siddha Âsana, the opener of the door of salvation. 37.
This Siddhâsana is performed also by placing the left heel on Meḍhra (above the male organ), and then placing the right one on it. 38.
Some call this Siddhâsana, some Vajrâsana. Others call it Mukta Âsana or Gupta Âsana. 39.
Just as sparing food is among Yamas, and Ahiṃsâ among the Niyamas, so is Siddhâsana called by adepts the chief of all the âsanas. 40.
Out of the 84 Âsanas Siddhâsana should always be practised, because it cleanses the impurities of 72,000 nâḍîs. 41.
By contemplating on oneself, by eating sparingly, and by practising Siddhâsana for 12 years, the Yogî obtains success. 42.
Other postures are of no use, when success has been achieved in Siddhâsana, and Prâṇa Vâyû becomes calm and restrained by Kevala Kumbhaka. 43.
Success in one Siddhâsana alone becoming firmly established, one gets Unmanî at once, and the three bonds (Bandhas) are accomplished of themselves. 44.
There is no Âsana like the Siddhâsana and no Kumbhaka like the Kevala. There is no mudrâ like the Khechari and no laya like the Nâda (Anâhata Nâda.) 45.
