The Vedas recommend many ritualistic ceremonies to be performed with ones wife, on the birthdays of ones 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, jnatva sastra-vidhanoktam: everything must be performed as indicated in the sastras. For Kali-yuga, the sastras enjoin that sankirtana-yajna be performed always: kirtaniyah sada harih [Cc. adi 17.31]. All the ritualistic ceremonies recommended in the sastras must be preceded and followed by sankirtana. This is the recommendation of Srila Jiva Gosvami.
