According to Vedanta the jiva experiences three states viz
- Jagrat (waking state)
- Svapna (dreaming state)
- Sushupti (deep sleep state)
My question is regarding the third state that is Susupti.
According to vedanta in this state working as well as knowledge acquiring senses becomes totally inactive along with mind and ego.
But we experience that we wake up by hearing some sounds(say alarm) even from state of Sushupti.
Now the question arises, did person hear the sound and wake up or did he wake up and hear the sound?
If we say that the person hear the word and wake up then we will have to admit that he was not sleeping(by definition of Vedanta of Sushupti). And if we accept that after waking person heard the sound then we will have to also accept that sound did not wake the person up.
Contrary to views of vedanta is modern science which claims that even in deep sleep sound sensation is there but other sensations such as smell and taste is inactive.
In any case I'm interested in knowing the vedanta view on this.
What causes the person to wake up from state of Sushupti?
Is it external stimuli like sound etc or something else?
