So long as there is life, there must be action. We can understand this if we fix the meaning of words according to the Krama or method of reciting the text. The sacred books also tell us that action must cease; and we must understand what this really means. There are a variety of actions, but there can be only one action at a time. Action does not consist in a name; the law of one action at a time applies to all kinds of action; but it is the best action that can be performed at the time.
It is necessary to have knowledge to understand the law of Dharma; and we can understand it if we interpret the text correctly. In certain cases, however, it is easy to understand the whole idea.
