“There are two types of spiritualists and in the Sanskrit language one is called Bhajananandi and the other is called Ghosti Anandi.
Bhajananandi refers to one who personally likes to do spiritual activities, but are more reclusive and are concerned about their own salvation or liberation. Just by their being in the planet they are helping. But they don’t go about of the way to liberate other people. If someone looks them up and asks them, they’ll help them, but they more or less keep to themselves.
The other kind is called Goshti Anandi. He is a person concerned with liberating the whole world. He doesn’t want to go back to God alone, he wants to take as many people as possible with him.
So Krishna in the Bhagavad Gita says that a person who is teaching the Bhagavad Gita to the devotees, is the most dear to Him. Someone who is giving this knowledge to other devotees is the most dear. So you will find that a lot of devotees are very enthusiastic to give knowledge to others.HH Jayapataka Swami From the book: Taking Shelter of Krishna
