Why is a pure mind needed first?
First purity, then success
The sutra is: first purity (shuddhi), then accomplishment (siddhi). A pure mind is essential, and in Sundarkand Hanuman ji speaks of the person with a pure mind reaching Bhagwan, while deceit and guile are not liked.
First purity, then accomplishment; from accomplishment comes fame, from fame comes wisdom. To gain this, purity of mind is essential.
