If the idea of the meaningful is dropped, then you will see meaning in whatever you are doing in daily life. But we all have to have an idea of a better, more spiritual life. Whatever you want, even the so-called spiritual goals, is materialistic in value. If you want to achieve a spiritual goal, the instrument you use will be the same which you use to achieve materialistic goals, namely thought . So you are just thinking that there must be some purpose to life.
Spirituality is materialism.
In any event you do not act , you just think, which is to postpone. There is simply nothing else thought can do. That instrument called thought, which you are employing to achieve your so-called spiritual goals, is the result of the past. Thought is born in time, it functions in time, and any results it seeks are bound to be in and of time also. And time is postponement, the tomorrow.
