GUARD YOUR THOUGHTS
Sududdasam sunipunam yattha kamanipatinam
Cittam rakkhetha medhavi cittam guttam sukhavaham
The mind is very difficult to perceive; very delicate and subtle; it moves and lands wherever it pleases.
The wise one should guard his mind, for a guarded mind brings happiness.
Once, there lived in Savatthi the son of a banker. This young man asked the bhikkhu who used to come to his house for alms what he should do to be liberated from the ills of life. The bhikkhu instructed him to divide his property into three parts; one part to do business with, one part to support the family and one part to give in charity. He did as he was told and again asked what should be done next. So he was further instructed: firstly, to take refuge in the Triple Gem (Buddha, Dhamma and Sangha) and to observe the five precepts; secondly, to observe the ten precepts; and thirdly, to renounce the world and enter the Holy Order. The young man complied with all these instructions and became a bhikkhu.
As a bhikkhu, he was taught theAbhidhamma(Buddhist psychology) by one teacher and the Vinaya (rules of conduct) by another. Being taught in this way, he felt that there was too much to be learnt, that the disciplinary rules were too strict and too many, so much so that there was not enough freedom in the way of life of a bhikkhu. He thought that it might be better to return to the lay life. As a result of doubt and discontentment, he became unhappy and neglected his duties. He also became thin and weak. When the Buddha came to know about this, he admonished the young bhikkhu, 'If you can only control your mind, you will have nothing more to control; so guard your mind.
