In the Kashmir Shaivism system, Turiya is somewhat similar to the other three states, in that the actual experience of it comes and goes. We experiences wakefulness for some hours and then go to sleep. We dream for some hours and then go into dreamless sleep. Sometimes in meditation we enter into the Turiya state and then go into one of the other three states again. The system explains that the Turiya state must be held throughout all the other three states.
The Siva Sutras teach this. So it is to maintain that witnessing awareness, that subjective consciousness, throughout the other three states and in the midst of Turiya itself. Turiyatita is generally explained as nothing but this - Turiya successfully held or attained in such a way that one's experience of it never fades. This seems to have a direct synonomous relationship with nirvikalpa or sahaja samadhi. Posted by Anonymous to Feel Philosophy at 1:33 AM, July 11, 2009
