ADI PURUSH AVATAR (Incarnation as the Pre-eminent man):
Lord Vishnu took his first incarnation as the pre-eminent man, with a desire to commence creation. This first incarnation of Lord Vishnu was full of all the sixteen Kalas (Supernatural powers). Lord Brahma manifested from the navel of Lord Vishnu in his (Lord Vishnu) state of Yoganidra (deep meditation). The creation as well as the expansion of the creation commenced from the organs of Lord Brahma. The first incarnation of Lord Vishnu is all-powerful, which can be seen only by the yogins and sages who have attained divine knowledge. This incarnation is also the indestructible seed from which all the other incarnations manifest themselves. During the time of final annihilation of the world, every creation merges into him.
