Different organs of our body are governed by different devas. The solar plexus is connected with the sun, that’s why it is called the solar plexus. When the first rays of the sun fall on the solar plexus, it is very good for your body. This is why it is good to do Surya Namaskar (sun salutations yoga asana) in the early morning.
The solar plexus has a profound impact on the central nervous system, optic nerves, stomach and what we usually call “gut feeling”. It is the second brain in your body. Usually the solar plexus is slightly bigger than an almond. With the practice of yoga asanas, meditation, and Sudarshan Kriya, the solar plexus can become as large as an apricot. Then it performs better and balances the bodily functions.
When the solar plexus contracts, one feels horrible, sad, depressed; all the negative feelings come. When the solar plexus expands, the intuitive mind awakens; the mind becomes clear and focused.
Krishna was called Padmanabha, meaning whose navel is the size of the lotus flower. If you become Padmanabha, you become absolutely creative. Brahma, the Creator, is said to be born out of a blossomed solar plexus.
These days, the solar plexus remains small, but the tummy keeps getting bigger!
