Sri Nisargadatta Maharaj:

Real meditation is to abide in this sense of being. In fact, meditation means the sense of being holding on to itself. It is said that after death one goes to heaven or hell. But this is mere concept and hearsay. When a body has died, the indwelling atman, the sense of being, loses memory of its beingess and does not know "it is". In that state there is no sleep, waking and knowingness. 

You should understand this clearly. If one thinks one is the body, one becomes a slave of mind and suffers accordingly. Therefore, you should completely identify yourself with the highest principle in you, which is the knowledge "I am".

You think you are somebody; but you are nothing of the sort. The sense of being is expressed through the body as a consequence of the all-pervading Absolute. This sense of being is deeply infatuated with itself and is termed atma-prem, Self-love. It is also called guna, Shiva, and Brahman. It is the Self-love that is functioning through different bodies. Since there is only this principle expressing itself, in different ways, through the different vehicles, there is no "you", "I" or "he". When the body dies, it decomposes into the five primary elements; and the vital breath, prana, merges in the universal air. And the guna - that is, the sense of being - instantly becomes nirguna or non-being, just as a flame is extinguished instantly.
