Meditation is of three types: Sthoola Dhyana, Jyoti Dhyana and Sukshma Dhyana.
Sthoola dhyana (gross or physical meditation) is that in which one meditates on the physical form (of one’s ishta deva or diety).
Jyotirmaya dhyana (dhyana full of light) is that in which one meditates on or visualizes the brilliant flame form of Brahman.
Sukshma dhyana (subtle meditation) is on Bhraman as bindu, as kundalini shakti.
