Perceptual transformation

How do you propose we get this perceptual transformation?

It is not something that "we get," it is something that occurs by grace. How one best "prepares the ground" or otherwise attempts to make conditions conducive for the gracious event varies widely between humans -- for some it will be a simple sitting meditation, for some it will be the deliberate discovery of kundalini energies through a technical practice, for some it will be a deep philosophical enquiry that culminates in seeing the limits of the intellect itself, for some it will be the risky devotional commitment of bhakti with a beloved, trusted teacher, and for others the course of life itself suffices. There is no Swiss Army Knife [tm] of perceptual transformation.
