Very interesting and very well explained, Big Uncle.
I find that visualising things like this makes me easier and more meaningful to do DS prayers or meditation. When i was in a DS retreat a couple of weeks ago, i recites many malas of DS's mantra, but i found that i had nothing clear to visualise. But now i do, and now i will experience the full strength of reciting. Visualisation is the key to accepting blessings, and without it reciting the mantra isn't as effective. Thank you for the information. I will make use of it.
