I'm sure there are people here more
versed in Hinduism than I am, but it seems this is relatively un-noded. The
fundamental idea governing the
Hindu view of the world is the idea of a
cyclic universe. The universe is created by the
God of Creation,
Brahma. It is then sustained for a time by the
God of Sustenance,
Vishnu. Finally, the universe is destroyed by, who else, the
God of Destruction,
Shiva, only to be created again by Brahma. The cycle continues on for
eternity.
Compared to religions like Christianity and Islam, Hindus are a bunch of pretty laid-back dudes. The idea of spiritual oneness with all of creation is very important to the devout Hindu, and they only way to achieve true bliss* and escape the cycle of reincarnation (also a fundamental concept in Hinduism) is to realize this kinship with the universe and embrace it with your entire being.
*A mild disclaimer: The term "bliss" may actually apply specifically to Buddhism. My memory is a little fuzzy on the terminology, but suffice it to say that getting out of reincarnation is a pretty good thing, as your soul becomes re-incorporated into the a sort of "sea of creation" from which all souls are derived.
