संसारबन्धनिर्मुक्तिः कथं स्यान्मे दयानिधे ।इति या सुदृढा बुद्धिर्वक्तव्या सा मुमुक्षुता ॥ ९ ॥
In plain words
"How do I get completely free of the bondage of saṃsāra — you who are a storehouse of compassion?" When that question sets into an unshakable conviction, that is what we call mumukṣutā, the longing for liberation.
Close to the Sanskrit
"How may there be, for me, complete release from the bondage of saṃsāra, O treasury of compassion?" — that conviction which is thus, and is very firm, is to be called mumukṣutā.
