## Description of the Six Substances and Five Astikayas
**Verse 29 of the Time Commentary**
He is self-aware, omniscient, all-knowing, and sees all beings. He attains infinite, unobstructed, and formless bliss. ||29||
**Commentary:**
This verse supports the idea of the Siddha's (liberated soul) unconditioned knowledge, perception, and bliss. The soul's inherent nature is knowledge, perception, and bliss. In the state of samsara (cycle of birth and death), due to the contraction of the soul's power by the karmic impurities, it experiences limited knowledge, perception, and happiness through the senses. It experiences happiness that is dependent on external objects, bound by form, obstructed, and finite.
However, when all karmic impurities are destroyed, the soul's power becomes free and uncontracted. It then spontaneously and simultaneously knows and perceives everything (all substances, fields, time, and states). It experiences bliss that is independent, formless, unobstructed, and infinite. Therefore, the Siddha, who knows and perceives everything and experiences his own bliss, has no need for anything external. ||29||
