Your authentic experiences can be clouded by your mind and thus how your brain interprets events. Technically, the brain isn't even supposed to be handling these spiritual concepts. Its function is to command the body. With all these abstract spiritual events that occur in our lives, it is probable that the brain struggles to filter, arrange, and display these things to us...
Perhaps a reason that some people feel there is no critical analysis of the spiritual sphere that we are all engaing in, on various levels. Along with a bountiful exchange of practical knowledge and experience. It may simply be because the majority have aligned with incorrect concepts, perspectives, and practices.
Love between one another is a concern for all types of people, yet it seems many people take the passive seat in the arena of love; waiting for that special someone, waiting for the love to ignite and so on. However, what happens when we decide to create love? Why should we have to wait for it to 'feel just right' or for it 'just to happen'? Why can we not build the love from scratch?
Some food for thought:
Do we create philosophies and ways of understanding life simply because we do not know ourselves? Does a lion question what it is, or does it simply act, and thus live.
Can we forget about everything and simply live? Does the absence of a certain power in our lives cause us to fill that gap with various concepts and ideas?
Body - Brain - Mind - Spirit
So, if the body is based upon a physical existance, built towards efficiently navigating and manipulating the physical world - would spirituality, namely transcendance not be the enemy of the physical bodies' existance? Would the brain not find the very concept of transcendance to be offensive and a restriction upon the evolution of the physical body?
