परिपक्वं मनो येषां केवलोऽयं च सिद्धिदः ।गुरुदैवतभक्तानां सर्वेषां सुलभो जवात् ॥ १४४ ॥
In plain words
For those whose mind has ripened all the way through, this alone gives the fruit — nothing else is needed. And for everyone devoted to the teacher and to God, it comes easily, and it comes fast.
Close to the Sanskrit
Of those whose mind is fully ripened, this alone is the giver of accomplishment; and for all those devoted to guru and deity it is easily obtained, and swiftly.
