Bageshwar Dham Sarkar
How do I know if a friendship is good or bad?
Judge friendship by its result
Look at where a friendship leads: if it leads to worldly pleasure, it is bad, and if Bhagwan is discussed in it and it leads to meeting Him, it is very good. Friendship is not made to gain something.
If the result of your friendship is worldly indulgence, your friendship is bad; and if God is being discussed and God is being met through your friendship, your friendship is very good.
