Though these ethics are very conducive to a happy and peaceful life, we should not be contented merely with the second aspect of Buddhism. We should proceed to the higher aspects of Buddhism, the third aspect- the moral aspect. In the moral aspect, you must observe precepts, either five, eight or ten. The ten precepts are for novices (samaneras) while the 227 rules are for monks (bhikkhus). In daily life, we must observe at least the five precepts. When we can observe the five precepts perfectly, our morality is purified. When moral conduct is purified, a meditator can easily practise meditation, either Samatha or Vipassana meditation. Based on purification of moral conduct, a meditator can easily concentrate on the object of meditation and gain deep concentration, whereby the mind is clear, serene and happy.
