Gist of the teachings

Below is an article which gives a gist of Ramana Maharshis teachings

Happiness as what everyone is after, already tasted in sleep, and Self-enquiry ‘Who am I?’ as the chief means to it.
Consciousness as the screen behind waking, dream and sleep, and the mind as the ‘I’ that rises in the body and drops away in the Heart.
How to practise ‘Who am I?’ by asking to whom each thought arises, and surrender as either merging into the source of ‘I’ or giving oneself up to God.
Turiya beyond the three states, a Guru who need not be in human form, and God, Guru and the Self as one.
Self-realisation as simply being, the Heart, renunciation as a matter of the mind rather than surroundings, and fate and free will.
The jnani, and Arunachala Ashrama’s stress on sadhana, silence, and Bhagavan’s living presence as the Guru.

Michael James’s overview, The Teachings of Bhagavan Ramana, opening with the question Who am I? and whether we really are the person we seem to be.
Whether anything we perceive can be known as real without knowing ourself, the perceiver, and why intransitive awareness ‘I am’ is more basic than awareness of objects, as sleep shows.
Happiness as our own being, and why the stilling of the mind in sleep is only temporary unless ego itself comes to an end.
Self-investigation as ‘always keeping the mind on oneself’, from Nan Ar?, with ego subsiding back into our being as we attend to ourself.
Self-attentiveness as self-surrender too, from the thirteenth paragraph of Nan Ar?, and what ‘God’ means there.
Ulladu Narpadu verses 25 and 26 on ego grasping form and on giving up ego as giving up everything, and the love for this practice growing by grace.
