What is the ultimate religious goal for Hindus and Buddhists, and why do they seek it? What is the ultimate religious goal for Hindus and...

I think
that both methods of religious worship are very similar, but I also believe that one makes a
slight mistake in combining the two.  The absence of creative deities in one and their dominant
presence in the other might help to bring some distinction between the two.  Indeed, there is a
similar understanding of comprehending existence as one where one's modern state is a reflection
of past lives or previous forms of existence.  The ultimate religious goal in this realm is to
understand who we are in light of who we were and act accordingly so that we do good works in
this life that can help us recognize the universal Atman that awaits later on in next lives. 
What we do in this life will have meaning towards our soul's journey or recognition towards this
universal soul and the closer we can move to it in this life, the greater the chance our soul
will experience Moksha, or liberation.  This becomes the ultimate religious goal, although both
forms of worship have slightly different understandings about the role of the divine and
specific deity worship in such a process.
