Samadhi means sleep in waking state (jagrat sushupti). Bliss is overpowering and the experience is very clear, whereas it is different in sleep.

Devotee:  Horripilation, sobbing voice, joyful tears, etc., are mentioned in Atma Vidya Vilasa and other works. Are these found in samadhi, or before, or after?

Ramana Maharishi:  All these are the symptoms of exceedingly subtle modes of mind (vrittis). Without duality they cannot remain. Samadhi is Perfect Peace where these cannot find place. After emerging from samadhi the remembrance of the state gives rise to these symptoms. In bhakti marga (path of devotion) these are the precursors to samadhi.

Devotee:   Are they not so in the path of jnana?

Ramana Maharishi:  May be. There is no definiteness about it. It depends on the nature of the individual. Individuality entirely lost, these cannot find a place. Even the slightest trace of it being present, these symptoms become manifest. Manickavachagar and other saints have spoken of these symptoms. They say tears rush forth involuntarily and irrepressibly. Though aware of tears they are unable to repress them. I had the same experience when I was staying Virupaksha cave.

Devotee:   Sleep state is said to be the experience of Bliss, yet, on recollecting it the hairs do not stand on end. Why should they do so, if the samadhi state is recollected?

Ramana Maharishi:  Samadhi means sleep in waking state (jagrat sushupti). Bliss is overpowering and the experience is very clear, whereas it is different in sleep.

Devotee:   Can it be that the recollection of happiness in sleep is not clear and so there is no horripilation, etc.?

Ramana Maharishi:  The Bliss of samadhi is a perfectly clear experience and its recollection also is similar. But the experience of sleep is otherwise.
