This is a cross between Hathasiddhasana and Muktasana so far as the arrangement of the heels is concerned and is for that reason often referred to as a variation of Siddhasana. In this pose, when placing the heels, first remember to place one against the public bone, somewhat horizontal, so as to cover the genitals completely and then place the other heel across the frist near the arch of the foot. The purpose is to cover the genitals. In this the soles are tuned upward and the upper surface of the feet touches the ground instead of pressing the same against the opposite thigh as in the case of previous postures. The hands may be arranged as convenient. Hold the body straight, the spine and the neck erect.

It is called Guptasana or the secret pose probably as it protects the sex organs from view or it may be that few students guarded its knowledge and passed it on as a hidden secret posture. Guptasana may be practiced either in the morning or in the evening for a period of five to ten minutes. In the case of spiritual students there is no time limit. Persons suffering from hydrocele and other complication of the lower abdomen like hernia etc should avoid such Asanas as they require the heels to be pressed against the reproductive organs and take to other simple meditative poses which are free from this technique.

The hiding of the two feet under the thighs and then placing the anus over the feet is regarded by some authorities as the real Guptasana. Since this is inconvenient and partly impracticable, we recommend the previous technique which is in general use.
