There is an anecdote. Someone was trying to catch a black cat in a dark room which was not there.
First of all, you think there is a cat and then you try to catch it. The first assumption that you don’t love yourself is itself wrong. You ARE Love. When you think I don’t love myself, and make so much effort to love yourself, it results in total failure. I tell you, you cannot make an effort to love, either yourself or anybody. You simply have to relax and realize that you are love. Got it?
Even the person who wants to commit suicide and thinks he doesn’t love himself, loves himself much more. He loves pleasure so much that he is unable to go through a little discomfort. That is why people commit suicide.
By committing suicide you will not get out of discomfort. It is like removing your jacket when you are feeling so cold. You are feeling so cold and you remove your jacket. How does it help? Simply realize that you are love. Don’t try to love yourself, just relax. The best way is pranayama and mediation. Breathing exercise and meditation.
Just be natural and accept people. Love is always about giving. Know that you have come here (on the planet) to only give love and not demand love from anybody!
