Sometimes a person, the proprietor of the house, after death, remains in that house as serpent, sometimes as dog, sometimes as tree. Being too much attached to the possession, they cannot get better life. And sometimes we can get the body of a hog and monkey in Vrndavana also.
From Srila Prabhupada’s lecture on Srimad-Bhagavatam 1.2.23 — Vrndavana, November 3, 1972
