A person who is a householder but is initiated by a sannyasi has the duty to spread Krsna consciousness at home; as far as possible, he should call his friends and neighbors to his house and hold classes in Krsna consciousness.

Holding a class means chanting the holy name of Krsna and speaking from Bhagavad-gita or Srimad-Bhagavatam. There are immense literatures for spreading Krsna consciousness, and it is the duty of each and every householder to learn about Krsna from his sannyasi spiritual master.
