Four Dhyana Realms
First Dhyana Realm - One is reborn within the Three Brahma Abodes in this First Dhyana Realm by cultivating the four immeasurables and the firelike concept and discernment.
Second Dhyana Realm - Being further accustomed to these states, one is reborn in the Three Abodes of Radiance within the Second Dhyana Realm, with its waterlike joy and bliss.
Third Dhyana Realm - Being further accustomed to these states, one is reborn in the Three Abodes of Goodness within this Third Dhyana Realm, with its windlike inhaling and exhaling of breath.
Fourth Dhyana Realm - Being further accustomed to these states, one is reborn in either of the three flawless abodes within the Fourth Dhyana Realm--Cloudless Light and so forth. By increasing an undefiled state by meditating on this forth dhyana, one takes rebirth within the Five Pure Abodes, depending upon whether this cultivation is lesser, medium, great, greater, or extremely great.
