When you say, ‘I shall not be envious,’ you have introduced the factor of time. When you say, ‘I will not be envious,’ you are taking time: in a few years, or sometime later, I will get rid of envy. When you introduce time, the continuity of envy goes on – you don’t get rid of it. You are still envious when you say, ‘It should not be.’ So envy has to be cut immediately, and it can be cut immediately only when you see the thing, when you see envy.
