Meditation and self-hypnosis are effective tools towards building your self into something else, something greater than it is.
This takes research, learning how to enter meditative states requires practice, effort. It isn't something you can pick up quickly, it doesn't work overnight. You've got an entire lifetime of mental activity going on, and it's so easy to delve into that, than it is to bring it to a close. Silencing the mind is like it's death.
The mind makes a lot of effort to convince you that it's you, that you are the mind. By silencing it, you become aware that you are something beyond it, that it's a tool, rather than master. This is a kind of death to your perception of what defines you. There is a you beyond the parts that define you externally. There's something deeply internal, an awareness that exists there, separate from the chattering mind.
