Discussion

The name comes from the training that produces it: a meditator on the fourth dhyana enters the preparation for Infinite Space and considers that the conception of Form is coarse and must be abandoned--there is only infinite space. Once the actual Formless absorption is attained, it does not necessarily dwell on such thoughts--at that point it may take any element of dharma as its focus. DKC
