आद्यां सर्वादिभूतब्रह्मविषयां विद्यां वदसि हि सत्यरूपां
In plain words
What you are speaking of is the first knowledge of all: the vidyā whose one object is Brahman, the origin of everything — the knowledge whose very form is truth.
Close to the Sanskrit
The primal knowledge, whose object is Brahman that is the origin of all, whose form is truth — that indeed you speak.
