Look at the problem our position creates for us even in this. We are not able to ake even this prayer (prarthana) on your behalf with "anjali" (use of hand). When you perform namaskara to us, we ourselves give "asirvadam". You also expect us to do so.
If we say that we also have to do namaskara to another (nr0 and "try to tap" that source for giving the blessing to you, you will be disappointed. One feels comfortable only if the blessing comes immediately from the person to whom the namaskara is done.
So, even though mentally we transmit your namaskara to Narayana, our hand which should be turned in "anjali" to Him, has to turn to you in the "asirvada" mode.
All these years, you have been coming in numbers everyday and performing namaskara to me.
I, for my part, have been trying to do my utmost by way of mentally praying to Him on your behalf and for your good. Even then, if any of your prayers have borne fruit, more than my effort, it is due to your faith. I think that the "sincerity" of my prayer on your behalf cannot match your limitless faith in me.That is why I said that even your thinking that you get the fruit of my blessing is the fruit of your own faith.
In the ultimate analysis, the only cause for the fulfillment of your prayer is Narayana's compassionate Grace toward you, which is yours without my "vakalat".
