Try to understand what meditation is. Compassion can become a criterion as to whether the meditation was right or not. If the meditation has been right, compassion is bound to come — it is natural; it follows like a shadow. If the meditation has been wrong then compassion will not follow. So compassion can work as a criterion as to whether the meditation has been really right or not. And a meditation can be wrong. People have a wrong notion that all meditations are right; It is not so. Meditations can be wrong. For example, any meditation that leads you deep into concentration is wrong — it will not result in compassion. You will become more and more closed rather than becoming open. If you narrow down your Consciousness concentrate on something, and you exclude the whole of existence and become one-pointed, it will create more and more tension in you. Hence the word ‘attention’. It means ‘at-tension’. Concentration, the very sound of the word, gives you a feeling of tenseness.
