I do visualizations now and then, as part of the integral practice. A beautiful default visualization is to visualize all beings awakening. Otherwise, it can be anything that supports life for others or myself (supporting life as best I can tell, which may not be very well – but the intention is there at least).
Some aspects of the visualizations…
(a) They come alive here/now, as if it is already happening.
(b) They are in the direction of vividness and details.
(c) I let go of them when I am done.
