FYI Thundar, let me teach you a lil about Buddhism:
You seem to only be familiar with the surface concepts. However, your beleif that Buddhism is a self centered philosophy is so wrong, so painfull incorrect.
Buddhism is the opposite of self centeredness.
Samsara is the opposite of Nirvana, the cycle of birth and re birth, which we continue to endure for as long as we desire the attachments to this world and beleive in our own ego. To beleive in a self, to beleive that we are individual and independent of all others, is a falsehood according to Buddhism.
This beleif in a self, is what keeps us trapped in Samsara. To ever reach Nirvana, which is union with all things and the death of this illusion of self and detachment from all other reality, we must let go of the concept of ego.
According to Buddhism, the "self" is nothing more than a composition of the Five Aggregates, which is why Buddhists do not beleive in a soul.
