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.
The 5 indriya are spiritual faculties that become activated by feeling them in the body. Starting with faith –the pivotal faculty for coming out of the personal and sensory realm – and culminating in wisdom – the ability to discern skillful from unskillful, non-stress from stress – these 5 indriya work to release the mind from the pressure of identity.
