This also is a special quality of the soul that it fills the body, and extends through all space and encloses it within itself (महतो महीयान्); by thinking so, the yogi by a mere respiration of air makes his body round and turgid as a frog, and comprehends the universe in himself. [Sidenote: 3. Lightness or _Laghimá_.] From thinking on the lightness of the soul, the yogi produces a diminution of his specific gravity by swallowing large draughts of air, and thereby keeps himself in an aerial posture both on sea and land. This the Sruti says as (लघोर्लघीयान्). [Sidenote: 4. Gravity or _Garimá_.] This practice is opposed to the above, and it is by the same process of swallowing great draughts of air, and compressing them within the system, that the yogi acquires an increase of his specific gravity or _garimá_ (गुरोगरीयान्). Krishna is said to have assumed his बिश्बम्भर मूर्त्ति in this way, which preponderated all weights in the opposite scale. [Sidenote: 5. Success or _Prápti_.] This is the obtaining of desired objects and supernatural powers as by inspiration from above. The yogi in a state of trance acquires the power of predicting future events, of understanding unknown languages, of curing divers diseases, of hearing distant sounds, of divining unexpressed thoughts of others, of seeing distant objects, or smelling mystical fragrant odours, and of understanding the language of beasts and birds. Hence the prophets all dived into futurity, the oracles declared future events, Jina understood _pasubháshá_, and Christ healed diseases and infirmities. So also Sanjaya saw the battles waged at Kurukshetra from the palace of king Dhritaráshtra. [Sidenote: 6. Overgain—_PraKámya_] Prakámya is obtaining more than one’s expectations, and consists in the power of casting the old skin and maintaining a youth-like appearance for an unusual period of time, as it is recorded of king Yayáti (Japhet or Jyápati); and of Alcibiades who maintained an unfading youth to his last. By some writers it is defined to be the property of entering into the system of another person; as it is related of Sankaráchárya’s entering the dead body of prince Amaru in the Sankara Vijaya. [Sidenote: 7. Subjection _Vasitwam_.]
