मन्दमध्यमरूपापि वैराग्येण शमादिना ।प्रसादेन गुरोः सेयं प्रवृद्धा सूयते फलम् ॥ २९ ॥
In plain words
Even if that longing starts out faint or middling, it can still ripen — nourished by growing dispassion, by calmness and its companion virtues, and by your teacher’s grace — until, grown strong, it bears its fruit.
Close to the Sanskrit
This [longing for liberation], though of mild or middling degree, having grown intense through dispassion, calmness and the rest, and through the teacher's grace, yields its fruit.
