I object to that poor excuse that man ‘believes’ in god because of fear of death, or the unknown, or some other mambo jambo.
Spirituality is innate in humans. It has continually shown itself during the course of humanity, in infinite ways and variations, from worshiping nature to actually becoming god-realized.
It’s not even about belief. It is simply being aware that the human mind is not the ultimate instrument in the universe, and many phenomena are much beyond it.
