When the seer does not see any doer besides the guṇas, and also perceives That which transcends the guṇas, then he attains My state (attains the Supreme).
This is a fundamental statement. It contains all spiritual instructions to gain liberation. It also defines the right perception about the world.
Nature propels all activities through its gunas. This is the message Krishna conveyed right in the 3rd chapter. Be guided accordingly. Do not condemn any activity. Instead, ascribe it unreservedly to Prakrti.
But gunas work around a pivot, which they cannot touch at all. While all actions are from Nature, the inmost presence is above the gunas. See everyone as that pivotal presence, the Soul. You will then have no occasion to blame or condemn anyone or anything.
Drop all preferences and prejudices, and be free inwardly. The means for this is the two-fold spiritual wisdom: Gunas are Nature’s, and the Soul is transcendental, unaffected by Nature’s activities. One with this perception attains the Supreme, says Krishna.
