Ramana Maharshi is unique kind of saint who is appropriate for the 20th centuary. Unlike the traditional hindu saints Ramana is oriented in "Who Am I" teaching. He showed the way as self-enquiry for self realisation.
Ramana is as like everybody in childhood days. When his father died he thought differently as who is dying and what happened to his father's body and soul. He got realised that the body is not a true one and the soul
residing inside the body is the true one.

His Teachings: (find your soul or get surrender)

Ramana Maharshi, perhaps modern India's greatest sage, recommended Atma-Vichara or Self-inquiry as the best and most direct approach for Self-realization. This has caused some to think that he regarded other yogic practices, like mantra or pranayama, as unimportant or even useless. However, a careful examination of his teachings reveals that he recommended various yogic approaches of devotion, mantra or raja yoga - in fact, he encouraged whatever might aid a person in their sadhana.

The Maharshi did not put much emphasis on the outer formalities of practice for Self-inquiry. This has similarly caused some to think that for Self-inquiry there are no prerequisites - that any one at any stage of life or following any life-style can do it and succeed. Again, a careful examination of his life and teachings shows that he never discountenanced the ethical and ascetic basis for Self-inquiry

"Your true nature is that of infinite spirit. The feeling of limitation is the work of the mind. When the mind unceasingly investigates its own nature, it transpires that there is o such thing as mind. This is the direct path for all."
—Ramana Maharshi

Ramana's main teaching is that one is self-enquiry and the other is surrender to god. He himself a great devotee of Lord shiva in the form of Mountain Arunachala.
He wrote "Arunachala Aksharamana Malai" which has 108 two line songs which is devoted to Lord
Arunachala.
He is very much confident that the 'Bhakti'(love towards god) is very important and easy way to
attain self-realisation in the present world.
