Recently I was present at an interview given by the Venerable Masoyein Sayadaw, who is virtually the Sangha Raja or Thathanabaing of Burma, to some Buddhist monks of European origin. His advice to them is "Of course, you must learn the Dhamma during your stay there. But I would stress the importance of practice. Strive to be free from craving. If you succeed appreciably, you will be able to do a lot for your fellow-men when you return to your countries."
In the very first sermon, Dhammacakka pavattana Sutta,* the Buddha proclaims, "What, O monks, is the origin of suffering? It is that craving which gives rise to ever fresh rebirth and, bound up with pleasure and lust, now here, now there, finds ever fresh delight. It is the Sensual Craving (Kamma tanha), the Craving for Existence (bhava tanha), the Craving for Self-annihilation (vibhava tanha)."
In this talk, I do not propose to deal with the Craving for Existence, which is connected with the view of Eternalism, and the Craving for Self-annihilation, which is connected with the view of Nihilism. They require separate treatment.
So far as the Sensuous Sphere (kamma-loka) is concerned Sensual Craving is most harassing. There are six kinds of craving corresponding to the six sense objects: craving for sights, sounds, smells, tastes, bodily impressions and mental impressions.
To put an end to these cravings, at least to keep them under proper restraint, learning alone would not suffice. I can therefore understand fully why the Venerable Masoyein Sayadaw stresses the importance of practice of the Dhamma for the control and eradication of cravings.
