tasmims tvam ramaya sprsto
tat-sangad idrsim prapto
dasam papiyasim prabho
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear friend, when you enter such a body along with the woman of material desires, you become overly absorbed in sense enjoyment. Because of this, you have forgotten your spiritual life. Due to your material conceptions, you are placed in various miserable conditions.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When a person becomes materially engrossed, he has no capacity to hear about spiritual existence. Forgetfulness of spiritual existence entangles a man more and more in material existence. Such is the result of sinful life. Various bodies are developed with the material ingredients because of different types of sinful activities. King Purañjana assumed the body of a woman, Vaidarbhi, as a result of his sinful activities. Bhagavad-gita clearly says (striyo vaisyas tatha sudrah) that such a body is lowborn. If one takes shelter of the Supreme Personality of Godhead, however, he can be elevated to the highest perfection, even though he be lowborn. One acquires lower births when one’s spiritual intelligence is reduced.
