Sri PBA Swami's Sarartha Deepikai:
With this, the greatness of this means as compared to the other means that have been given up, is told.
What is that greatness?
Those dharmas have to be performed by the chetana. Therefore they realize their nature only through the chetana's effort. As this means is eternal, it is already accomplished. They are of the form of knowledge and effort. This one is distinguished and of supreme power. Because they are due to the effort of the chetana, they are fraught with danger. Since this is an accomplished means, it has no danger. Those means are not appropriate to the nature of the chetana. This one is most appropriate. They are dependent on each other. This is independent of anything.
Since the other means are due to the effort of the chetana, they are attached to him for their existence. As they do not have the knowledge of what they need to do for the chetana nor do they have the power to do it, they are dependent on the Lord to complete their task. But this means is opposite to those means, is complete and full of power. Therefore, it is not dependent on anything.
