Introspection is seeing within. It is an encounter with direct experience while the mind acts as a bystander. It starts with cleaning up of the slate of conditioning by simply ignoring that which the mind throws at us. When we ask a question and demand an answer in the form of a direct experience, we get the pure and unadulterated truth. In this meeting we will try to see our own essence via introspection.
Since all experiences are mediated via the mind, which distorts what is into a subjective impression of it, all we can experience is necessarily a distortion. That means, we cannot know what is, we only know that which is not. It also means, all we can have is ignorance, not knowledge. Any knowledge is refined ignorance, nothing more. Reality stands on the foundation of ignorance and is unknowable.
Reality is experience, and there is a conscious background of it - the Self, the experiencer, or the consciousness. There is no separation between the experience and the experiencer. Although, there is an illusion of separation created by the mind, which divides the wholeness of the reality into multiple kinds of experiences. It also creates the division of the experience and the experiencer. When we see through this illusion, we find that the Self, and the reality are one, and identical. This is the greatest realization a human can have.
A slightly unconventional and introductory view on what death is and what it is not. It seems that the death is largely misunderstood as an event of decay and destruction. Here we find that death is a tiny but important part of the continuous flow of experiences we call life. The opposite of death is birth, life has no opposites.
