Premanand Maharaj Ji
How can I tell if my love is selfish?
If it ends when wishes are blocked, it was selfishness
If it is "I want you, you want me, I fulfil your wishes and you fulfil mine", and love ends when something blocks that, it is pure desire, selfishness and ignorance. Love is a very great thing.
I want you, you want me, I fulfil your wishes, you fulfil mine. If there is an obstacle in fulfilling the wishes, love ends.
