Most Happiest Thing In The Universe Is Self Realization !

...the so called many Atmans(souls) or many spirits are but the partial manifestations of one universal Atman, or a universal Spirit, whom we call God, and who is worshipped by different names in different countries – by some as our Father in heaven, by others as Brahman, Allah, Christ, Buddha, and so forth. We are by our birthright, as it were, immortal and divine. Our true nature is changeless… Birth, growth, decay and death can affect only the gross form. But that which is beyond the physical body, that which is the illuminator of the subtle body, is free from all change; as such It is immortal and eternal. That Atman(soul) is the real individual in us.
~Swami Abhedananda
