Ramana Maharshi explains the connection between Self And Tripadis(knower, known and knowledge)

Devotee:

How do the triple factors (i.e., knower, known and knowledge), which are absent in deep sleep, samadhi, etc., manifest themselves in the Self (in the states of waking and dreaming)?

Ramana Maharshi:

From the Self there arise in succession

(i) Chidabhasa (reflected consciousness) which is a kind of luminosity.
(ii) Jiva (the individual consciousness) or the seer or the first concept.
(iii) Phenomena, that is the world.

Devotee:

How can there be a connection between the Self which is pure knowledge and the triple factors which are relative knowledge?

Ramana Maharshi:

CINEMA SHOW	SELF
The lamp inside (the apparatus)	The Self
The lens in front of the lamp	The pure (sattvic) mind close to the Self.
The film which is a long series of (separate photos).	The stream of latent tendencies consisting of subtle thoughts.
The lens, the light passing through it and the lamp, which together form the focused light.	The mind, the illumination of it and the Self,which together form the seer or the Jiva.
The light passing through the lens and falling on the screen.	The light of the Self emerging from the mind through the senses, and falling on the world.
The various kinds of pictures appearing in the light of the screen.	The various forms and names appearing as the objects perceived in the light of the world.
The mechanism which sets the film in motion.	The divine law manifesting the latent tendencies of the mind.

Just as the pictures appear on the screen as long as the film throws the shadows through the lens,so the phenomenal world will continue to appear to the individual in the waking and dream states as long as there are latent mental impressions. Just as the lens magnifies the tiny specks on the film to a huge size and as a number of pictures are shown in a second, so the mind enlarges the sproutlike tendencies into tree-like thoughts and shows in a second innumerable worlds. Again, just as there is only the light of the lamp visible when there is no film, so the Self alone shines without the triple factors when the mental concepts in the form of tendencies are absent in the states of deep sleep, swoon and samadhi. Just as the lamp illumines the lens, etc., while remaining unaffected,the Self illumines the ego (chidabhasa), etc., while remaining unaffected.
