Energy has to be cultivated as a resource for practice. This process has three stages: gathering, specific application, and the strength that can release obstacles. The thinking mind uses energy but cannot generate it; energy is generated in the heart (citta) and in the body. Apply energy to empty out the negative and unskillful – the good and bright will arise on its own.
Sati – mindfulness – is only mentioned once in the Ānāpānasati sutta. ‘Directly feeling and knowing’ – pajānati – is the mode of practice. When we’ve attuned to this, we move to ‘training’. This phase of ānāpānasati begins with training in deeper sensitivity of the entire body.
Wisdom is the know-how faculty that discerns suffering and its end. It knows how the 3 intelligences (verbal, emotional, bodily) can work together to bring about the stilling of saṇkhāras. From it noble knowledge – realization – arises.
