Sat-darshana Bhashya (translation)

Verse 24.

धिये प्रकाशं परमो वितीर्य
स्वयं धियोऽन्तः प्रविभाति गुप्तः।
धियं परावर्त्य धियोऽन्तरेऽत्र
संयोजनान्नेश्वरदृष्टिरन्या॥

The Supreme gives the light to thought. Within it, Himself hidden, He shines. Hence to turn in the thought to unite within, that is to see the Lord. How else to see?

The Supreme Lord, the Creator, is Himself consciousness; and when by the force that is inherent in and inseparable from the consciousness various forms of it are created, the light of the consciousness lends its support to them for their sustenance. But this consciousness being the cause of all causes, subtler than the subtle, it lies hidden in thought, i.e., the mind, at the same time supporting its movement. So if the diffused mind with its scattered thoughts, gathers itself up and gets in to discern the light that supports it, what remains is the consciousness of the Lord that has become the Self. Therefore to withdraw from the Outer and turn to the Inner is to see the Self and to unite with the Lord, whose light is the controlling and directing principle of the thought-mind.

The next three verses discuss the character of the ego.
