Yoga Sutra 3.14 Essence and characteristics.
The world is real and every object has an underlying essence.
Does the essence of an object exist as a pure idea somewhere beyond physical reality?
Or, is that essence purely physical? In that case, does the essence of something relate to its DNA?
Or, does the essence of an object manifest as a result of the interaction between awareness and the natural world?
If your ways of being change continually, who is noticing these changes?
