Lord Chaitanya: Pastimes of Lord Chaitanya

                                                                  Q. Once in Krishna Consciousness or devotional service, do we have to offer food and water to forefathers periodically? If not, then why did Caitanya Mahaprabhu go to Gaya for sraddha ceremony? In one purport, Srila Prabhupada says that if offerings to forefathers are stopped, generations of family members remain in hell. Is this true for devotees also?
