FOUR TRUTHS

IV. 2. There the Blessed One addressed the brethren, and said: ‘It is through not understanding and grasping four truths[2], O brethren, that we have had to run so long, to wander so long in this weary path of transmigration–both you and I.’

‘And what are these four? The noble conduct of life, the noble earnestness in meditation, the noble kind of wisdom, and the noble salvation of freedom. But when noble conduct is realised and known, when noble meditation is realised and known, when noble wisdom is realised and known, when noble freedom is realised and known–then is the craving for existence rooted out, that which leads to renewed existence is destroyed, and there is no more birth.’

2. Or Conditions (Dhammâ). They must, of course, be carefully distinguished from the better known Four Noble Truths (Sakkâni) above, Chap. II, § 2.]
