When a perfect yogī desires to enter another’s body, he should meditate upon himself within the other body, and then, giving up his own gross body, he should enter the other’s body through the pathways of air, as easily as a bee leaves one flower and flies into another.
Purport
As air is inhaled into the body through the nostrils and mouth, similarly, the life air of the yogī’s subtle body travels through the pathways of external air and easily enters into the body of another person, just as the bee easily flies from flower to flower. One may admire a heroic man or beautiful woman and desire to experience life within their extraordinary material body. Such opportunities are available through the mystic perfection called para-kāya-praveśanam. Pure devotees, being absorbed in meditation upon the spiritual form of the Supreme Personality of Godhead, are not actually attracted to any material body. Thus the devotees remain transcendental and satisfied on the platform of eternal life.

Translation
When a perfect yogī desires to enter another’s body, he should meditate upon himself within the other body, and then, giving up his own gross body, he should enter the other’s body by identifying with his subtle body and using the external air, just as a bee leaves one flower and flies into another.
One should meditate on being in another body. Giving up the gross body (piṇḍam), identifying with the subtle body, one enters another body by means of external air, just as a bee goes from one flower and enters another. This takes place by the power of concentrating on me. This statement of the previous verse should be added. This siddhi is called para-kāya-praveṣa.
