Joga Pradīpikā
[4] The Joga Pradīpikā covers a broad range of topics on yoga, including the nature of the yogic subtle body,[5] preliminary purifications,[6] yogic seals (mudrās),[7] asanas,[8] prānāyāma (breath-control),[9] mantras,[10] meditation,[11] liberation (moksha),[12] and samādhi.[13] One of the purifications in the text is the mulashishnasodhana, "the cleansing of the anus and the penis", which calls for water to be drawn into the anus and squirted out through the penis, which James Mallinson and Mark Singleton gloss as "a feat which is, of course, anatomically impossible.[15] The Joga Pradīpikā however asks the yogi to stay on as a physical body to serve the Lord, rather than choosing liberation.[11] On samādhi, the yogi reaches it by the "bee cave" in the sahasrara chakra, the "thousand-petalled lotus", with an unending "unstruck sound".Most of the asanas are said to bring therapeutic benefits; all of them ask the practitioner to direct the gaze (drishti) at the point between the eyebrows or at the end of the nose.
