Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O King Yudhisthira, at the time prescribed for reformatory ritualistic ceremonies for one’s self, one’s wife or one’s children, or during funeral ceremonies and annual death ceremonies, one must perform the auspicious ceremonies mentioned above in order to flourish in fruitive activities.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Vedas recommend many ritualistic ceremonies to be performed with one’s wife, on the birthdays of one’s children, or during funeral ceremonies, and there are also personal reformatory methods like initiation. These must be observed according to time and circumstances and the directions of the sastra. Bhagavad-gita strongly recommends, jñatva sastra-vidhanoktam: everything must be performed as indicated in the sastras. For Kali-yuga, the sastras enjoin that sankirtana-yajña be performed always: kirtaniyah sada harih. All the ritualistic ceremonies recommended in the sastras must be preceded and followed by sankirtana. This is the recommendation of Srila Jiva Gosvami.
