Friends:

What are the 5 Basic Rules Guiding Behaviour?

The Blessed Buddha once said to Anathapindika:
Whoever, householder, has not overcome five terrible evils, such one
is without morality, is without control and will be reborn in hell.
And what are those five terrible evils?
They are killing, stealing, sexual abuse, lying, and taking intoxicants.
But whoever has overcome these five terrible evils, such one is pure,
well controlled and will be reborn in a happy world.
One who is doing these 5 things, creates both present and future
extreme misery, and will thus experience much mental pain & regret!
One who abstains from these 5 things produces neither present nor
future terrible misery, nor will he experience mental pain or grief.
Such terrible evil is thus eliminated by him and extinguished in him...

Whoever murders living beings,
Speaks words that are not true,
Takes what does not belong to him,
Seduces wives of other men,
And takes intoxicating drinks or drugs,
To which he ever strongly clings:
A man who does not shun these evils,
Has no morality indeed;
And when his body once dissolves,
That fool will fall to deepest hell...
Who does no harm to anyone,
Who never utters any lie,
Who never takes what is not his,
Nor seduces his neighbour's wife,
Nor ever wishes in all his life
To drink intoxicating drinks:
A man who shuns these five evils
Is rightly called a virtuous man;
And when his body once dissolves,
This wise man rises heavenward.
