The dreaming state (svapna-sthāna), inwardly cognitive, having seven limbs, having nineteen mouths, enjoying the exquisite (pravivikta-bhuj), the Brilliant (taijasa), is the second fourth.

In plain words: The second state of the self is dreaming. Here the mind turns inward and experiences subtle, delicate things. This dreaming self is called Taijasa, meaning the bright or shining one.
