According to Vedic scriptures, a woman who dies with her husband, or enters into the fire in which her husband is burning, also enters the same planet her husband attains. In this material world there is a planet known as Patiloka, just as there is a planet known as Pitṛloka. But in this verse the word pati-loka does not refer to any planet within this material universe, for Pṛthu Mahārāja, being topmost amongst self-realized souls, certainly returned home, back to Godhead, and attained one of the Vaikuṇṭha planets. Queen Arci also entered Patiloka, but this planet is not in the material universe, for she actually entered the planet which her husband attained. In the material world also, when a woman dies with her husband, she again unites with him in the next birth. Similarly, Mahārāja Pṛthu and Queen Arci united in the Vaikuṇṭha planets. In the Vaikuṇṭha planets there are husbands and wives, but there is no question of their giving birth to children or having sex life. In the Vaikuṇṭha planets both husbands and wives are extraordinarily beautiful, and they are attracted to one another, but they do not enjoy sex life. Indeed, they consider sex not to be very relishable because both husband and wife are always absorbed in Kṛṣṇa consciousness and in glorifying and chanting the glories of the Lord.
