One of the few books written directly by Luangta, this meditation manual represents some of his clearest advice on developing the path.

The heart which is not controlled by a kammaṭṭhāna is liable to the arising of “outgoing exuberance” throughout life […which] has been the enemy of all beings for countless ages, and a person who wants to subdue the “outgoing exuberance” of his own heart will need to compel his heart to take the medicine – which is the kammaṭṭhāna.

While the book’s title goes against the usual presentation of “sila, samādhi, [then] paññā,” the idea that “wisdom develops samādhi” is supported by such suttas as SN 48.45.
