​Q: What is Samadhi? Ramana: In Yoga, the term Samadhi refers to some kind of trance, and there are various kinds of Samadhi. But the Samadhi I speak of is different. It is Sahaja Samadhi. For you remain calm and composed even while you are active, you realize that you are moved by the deeper real Self within. You have no worries, no anxieties, no cares. For, here you come to realize that there is nothing belonging to you, the ego. And everything is done by something with which you get into conscious union. Q: What is the difference between the bound man and the one liberated? Ramana: From the heart, there is a subtle passage leading to Sahasrara Chakra: Amrita-Nadi. The ordinary man lives in the brain unaware of himself in the heart. Jnana Siddha lives in the heart. When he moves and deals with men and things, he knows that what he sees is not separate from the one Supreme Reality, Brahman, which he realized in the heart as his own Self, the real. In Savikalpa samadhi, we lose physical body consciousness and experience the subtle body (Sukshma sharira). In Kevara-nirvikalpa samadhi, we know pure consciousness, bliss, the non-dual state. There is no mind, nor thoughts in trance (Turiya). In Sahaja samadhi, we experience enlightenment (Turiyatita), absolute freedom, emptiness. Non-attachment leads to stillness. No-mind is to go beyond the senses, thoughts, emotions and habits. No-mind gives intuition, wisdom and liberation. All phenomena are impermanent. True reality (Nirvana) appears when the ego ceases. Ego is selfishness, greed, fear, hatred and ignorance. It always clings to objects, to others and creates vanity, feelings of loneliness and insecurity. When the ego ceases, Buddha Nature appears. The five aggregates — body, sense, thought, mental habits, body-consciousness — are empty, they are not the Self. The Buddha taught that Shunyata, emptiness, is reality, Buddha Nature.
