Sanskrit – Meditation.
Dhyana
Dhyana is actual meditation. This is a state in which we have suspended the senses (step 5), withdrawing the attention inward and focused on something specific (step 6) and then totally become concentrated and absorbed in that concentration (step 7).
Dhyani Buddha
(Sanskrit) “Meditation Buddha.” Any one of the five symbolic aspects of the Buddha, often presented as “enlightened families” of Buddhas and Bodhisattvas. These five Buddha families symbolize the fully developed consciousness related to the purified skandhas. However…
“…there are five Dhyanis who are the “celestial” Buddhas, of whom the human Buddhas are the manifestations in the world of form and matter. Esoterically, however, the Dhyani-Buddhas are seven, of whom five only have hitherto manifested,* and two are to come in the sixth and seventh Root-races. They are, so to speak, the eternal prototypes of the Buddhas who appear on this earth, each of whom has his particular divine prototype.” —H.P.Blavatsky, The Secret Doctrine (1888)
