Video Information: Acharya Prashant speaking on the Shiva Sutras at a Shabdyog session at The 3rd Myth Demolition Tour, Rishikesh, on 27th February 2016

Shiva Sutra:

जाग्रत्स्वप्नसुषुप्तभेदे तुर्याभोगसंभवः (१.७)
Knowing what looks like as the difference
between the three states of consciousness,
one finds himself located in the Joy of the Fourth.

ज्ञानं जाग्रत् (१.८)
All Knowledge is confined to the waking state.

स्वप्नो विकल्पाः (१.९)
In the dream state, everything is imaginary.

~ शिवसूत्र
