वैराग्यबोधौ पुरुषस्य पक्षिव -त्पक्षौ विजानीहि विचक्षण त्वम् ।विमुक्तिसौधाग्रतलाधिरोहणंताभ्यां विना नान्यतरेण सिध्यति ॥ ३७५ ॥
In plain words
Understand this clearly, discerning one: dispassion and knowledge are your two wings, like a bird's. Neither one alone can lift you to the rooftop of liberation's palace — you need both together to reach that summit.
Close to the Sanskrit
Know clearly, O discerning one, that dispassion and knowledge are, for a person, like the two wings of a bird. The ascent to the summit-terrace of the palace of liberation is not accomplished without both — not by either one alone.
