A simple word for a complicated feeling. Have you ever felt completely empty without the drive, desire or thought of anything?
The lack of any feeling or emotion inside is explained by this word inanition. Great sages might have felt this almost impossible feeling. Meditation is the way to achieve this emptiness. And when you are absolutely empty or in inanition you will, get a chance to listen to yourself; the real self.
Difficult but not impossible. Bhagavad Gita calls it “jnana yoga” or the “way of knowledge” to finding the real self.
