Whatever thoughts come to the mind of a person whether to perform an action or not, depend on the consideration of the three categories of actions mentioned above. If it is sure that the action that a person is about to perform is certainly good, and to his righteous advantage, then pure (Rehmani) feelings will develop in his heart. He will get the urge to go ahead with the performance of the act. If you have such feelings about any act that you wish to perform, and you are sure that it is a hundred percent virtuous deed, and you don't have the slightest doubt or fear about its veracity, then you must go ahead doing it with full determination and firmness. Such actions are deemed obligatory to be performed tacitly.
