He who tries to develop universal love should try to possess various Sattvic virtues such as Kshama, patience, perseverance, tolerance, generosity, straightforwardness, mercy, truthfulness, Ahimsa, Brahmacharya, Nirabhimanata, etc. He should serve humanity untiringly with a disinterested, selfless spirit for many years. He has to kill his little self ruthlessly. He must bear calmly insults and injuries. Then only there is the prospect of cultivating cosmic love.

I have good news and I have bad news:

The bad news is that we have lost the key to the door
behind which the secret of life is hidden.

The good news is that it was never locked.
