Silence, Inquiry, Nisargadatta

What helps is silence. Look at yourself in total silence; do not describe yourself. Look at the being you believe you are and remember – you are not what you see. 'This I am not – what am I?' is the movement of Self-enquiry. There are no other means to liberation, all means delay. Resolutely reject what you are not, till the real Self emerges in its glorious nothingness, it’s 'not-a-thingness.'

(I AM THAT).

-- great summary of self-inquiry/atma vichara.
