Mbh 13.40.6c

This lady is incapable of being protected in the way in which other women are protected by men, since the chief of the celestials is endued with large powers of illusion. Alas, the situation in which I find myself is very critical. The behest of my preceptor should certainly be obeyed by me. If, therefore, I protect her by my Yoga-power, the feat will be regarded by all as a wonderful one. By my Yoga-power, therefore, I shall enter the body of my preceptor's lady. I shall stay within her and yet not touch her person, like a drop of water on a lotus-leaf which lies on it and yet does not drench it at all. If I be free from the taint of passion, I cannot incur any fault by doing what I wish to do. As a traveller, in course of his sojourn, takes up his residence (for a while) in any empty mansion he finds, I shall, after the same manner, reside this day within the body of my preceptor's lady. Verily, with mind rapt up in Yoga, I shall dwell today in this lady's body!' Giving his best consideration to these points of righteousness, thinking of all the Vedas and their branches, and with eye directed to the large measure of penances which his preceptor had and which he himself also was possessed of, and having settled in his mind, with a view only to protect the lady, to enter her person by Yoga-power. Vipula of Bhrigu's race took great care (for accomplishing his purpose). Listen now to me, O monarch, as I recite to thee what he did. Endued with great penances, Vipula sat himself down by the side of his preceptor's spouse as she of faultless features was sitting in her cottage. Vipula then began to discourse to her bringing her over to the cause of righteousness and truth. Directing his eyes then to hers and uniting the rays of light that emanated from her organs of vision with those that issued from his, Vipula (in his subtile form) entered the lady's body even as the element of wind enters that of ether of space.
