Blind faith is never required, neither questions should be in a mood of challenge. That should not. Questions or answers should be just to understand. And that should be accompanied with service. This is the mood. Whole Vedic process . . . nobody can deny in the Vedic process that there is no need of spiritual master. There is. So śraddhāvān. Therefore the faithful, the faithful can acquire knowledge.
And tat-paraḥ. Tat-paraḥ means we have to follow the faith favorably, not unfavorably. Just like the physician gives us some prescription, and he says that, "You do this, and do not do," so we have to follow the do-not's and the do's. In every field of action there are certain dont's and certain do's. So we have to follow.
Tat-paraḥ saṁyatendriyaḥ. And result of my knowledge is that one should be restrained in the matter of sense gratification. You cannot become progressive in spiritual life if you indulge in unrestricted sense gratification, because sense gratification is the cause of our bondage in this material world. And the whole treatment, progressive in spiritual life, is regulated. Of course, we have got senses, and the senses require some satisfaction. That is all right. There is no question of stopping the senses. It is not possible. If you want to stop the work of the senses, that is not possible. Simply we have to purify the senses.
