There are vasanas in the latent state even in trance. The vasanas must be destroyed.

Ramana Manarhisi:  Visions and thought-currents are had according to the state of mind. It depends on the individuals and not upon the Universal Presence. Moreover, they are immaterial. What matters is Peace of Mind.


D.: Peace of mind is the result of trance. How is trance got?


Ramana Manarhisi:  Trance is only absence of thoughts. That state prevails in sleep. Do you have enduring peace of mind on that account?
….


Ramana Manarhisi:  Trance is only temporary in its effects. There is happiness so long as it lasts. After rising from it the old vasanas return. Unless the vasanas are destroyed in sahaja samadhi (effortless samadhi), there is no good of trance.


D.: But trance must precede sahaja samadhi?


Ramana Manarhisi:  Trance is the natural state. Although there are activities and phenomena, yet they do not affect the trance. If they are realised to be not apart from the Self, the Self is realised. Where is the use of trance, unless it brings about enduring peace of mind? Know that even now you are in trance whatever happens. That is all.


D.: If trance be my natural state, why is it said that trance is necessary to be got before Realisation?


Ramana Manarhisi:  That means that one should be aware of his eternal state of trance. Inattentiveness to it is ignorance. Pramado vai mrtyuh (inattention is death itself).


D.: How can I be attentive without getting trance beforehand?


Ramana Manarhisi:  Very well. If you are so anxious for trance any narcotic will bring it about. Drug-habit will be the result and not liberation. There are vasanas in the latent state even in trance. The vasanas must be destroyed.
