"The soul mate is what we aspire to and like to understand about us, is what we deem to be perfection, purity and endless regarding our own being."
- In this context are you refering to the soul? or to one's soulmate?
I read your sentence as:
Mate, the soul is what we aspire to and like to understand...
But I can also interprete this as a soulmate. except that it is harder for myself to understand that sentence...if I think its refering to one' s own soulmate.
