Commentaries and Reflections

Commentary by S Ramaswami:

“How can you see an object in its totality?
An object is made up of the three Guṇa.
The predominance changes from moment to moment.
You see the Guṇa as one because of the closeness in the way they work.
Always one Guṇa predominates, supported by the other two.
Which depends on the type of action or quality of thought preceding it.”
