This variety of Siddhasana has been mentioned in the Hathayogapradipika and is especially practiced by the Kanaphata Yogins. It is variedly termed by the others as Vajrasana , Muktasana or Guptasana. This however is not technically correct since the postures last mentioned are practiced somewhat differently, and often with various symbols of Yoga. Suffice it to say here that Hathayogins favour this posture accordingly termed as Hathasiddhasana.

The difference in technique consists of mainly in the first placing, the right heel against the root of the generative organs, and then placing the left heel exactly over the right heel. While in the ordinary Siddhasana the heel pressure is divided between the perineum and the space above the generative organs, is to exert the pressure of both the heels over the root of the genital organs. Other directions for practice remain the same.
