Yoga Sutras of Patanjali translated by Yogi Kalinath - Chapter 4, Verse 14
Pada 4, Sutra 14
The reality of an object derives from the uniqueness of transformation.
The nature of existence, of expression through Prakriti, is one of constant flux through the action of the Trigunas. This is deemed to be a process inherent in Prakriti and follows a certain pattern for each object. This provides the background of stability for each object and hence their uniqueness according to their set pattern of unfoldment of expression (i.e. transformation).
Mind with its constant fluctuation is also an expression of Prakriti in flux with the Trigunas. Only beyond the states of the Gunas, Nirguna, can one experience Turiya, the undifferentiated state of consciousness.
