The only effort needed to know and experiences the truth is to practice the silence, which is meditation. Silence is releasing the mind, emotion, imagination and all outer identification with form.
Truth and silence reveal what exists beyond the mind. Silence is the ultimate awareness, because it reveals who and what we are in consciousness.
True silence is a surrendering of the ego and not a destruction of it.
To destroy the ego is to destroy our humanness and end our life in the body. Surrendering is a choice to let go of the ego in meditation and allow our awareness to guide and become us in consciousness. It is like leaving land and floating in the ocean, we are gently carried away into deeper awareness and consciousness.
