The most crucial prerequisite for the practise of dharma is complete isolation because when we are alone, we are subject to fewer distractions, creating the perfect conditions for sadness to grow in our minds.
For those who know how to use it, sadness is a fertile ground from which all kinds of beneficial thoughts can spring with very little effort.
Jigme Lingpa described sadness as one of the most invaluable kinds of noble wealth, and in the sutras Buddha hailed sadness as the trailblazer for all subsequent good qualities.
With sadness comes trust and devotion, which, once developed, mean the practises of shamatha and vipashyana require very little effort. Shamatha practise ensures that mind becomes malleable and workable, and a flexible mind makes vipashyana relatively easy to accomplish.
