The Practice of Metta Bhavana
Metta bhavana is the most universally beneficial form of discursive meditation, and can be practiced in any conditions. Thoughts of universal, undiscriminating benevolence, like radio waves reaching out in all directions, sublimate the creative energy of the mind. With steady perseverance in metta bhavana a point can be reached at which it becomes impossible even to harbor a thought of ill-will.
