Basically without misrepresentation of the scriptures of any religion is about virtuous living in contribution to benefit others and achieving a clear mind.
In Buddhism we talk about Karma, purification through virtuous acts to gain merits and attainments on our path to enlightenment. In developing humility we respect our Teachers as described (Vajrayana Doctrine) in the nine verses of Guru Devotion. The Guru gives us the methods and we work on ourselves.
It is doing the work on our own that (in my opinion)is the major difference in Buddhism in comparison to other major religions of the world. This work on self is called mind training for in believing in rebirth, it is the mind that comes back but the body that changes with each rebirth.
As for other major religions, the tenets is still about doing virtuous acts to gain a place of bliss with God. My only question on this simplistic way is that it is too easy to create in our mind a being like GOD and places all and everything on Him to do the hard work.
I used to go to church and had my education in a Christian missionary school and why I was never baptised was when I was told at a Sunday assembly, to walk down the aisle ask for forgiveness of my sins, get baptised and I will go to heaven to be with God. Easy way out.
Having said all the above, I still believe that when a person practises Bodhichitta (whether he or she knows it or not) will gain merits and will be born in a good place. And it is not confined to only Buddhists.
Bodhichitta is a Buddhism terminology and the meaning of kindness, compassion, care and love for others is universal.
