I am studying the jhanas and it says you can enter jhana without fully purifying the hindrances. I thought you can't reach the jhana without first fully suppressing the hindrance. How does one do that?
Here's what the book said.
When a bhikkhu enters upon a jhána without [first] completely suppressing lust by reviewing the dangers in sense desires, etc., and without [first] completely tranquillizing bodily irritability37 by tranquillizing the body, and without [first] completely removing stiffness and torpor by bringing to mind the elements of initiative, etc., (§55), and without [first] completely abolishing agitation and worry by bringing to mind the sign of serenity, etc.,  and without [first] completely purifying his mind of other states that obstruct concentration, then that bhikkhu soon comes out of that jhána again, like a bee that has gone into an unpurified hive, like a king who has gone into an unclean park.
