His practice is meditation on mind by my understanding.
He advices most relaxed attitude towards your daily practice.
Just pay attention of where is the mind at present moment.

This is an different approach than meditate on breath or mantra.
For a people with active/energetic mind, and find it too boring to
solely focus on breath, his approach might be great of help.
