It is called Mahaddivya and was created at the beginning of the Yuga. In it existed the true Light, Brahma, the eternal One, the wonderful and inconceivable Being, the omnipresent, invisible and subtle Cause, the Entity and Nonentity-natured Self.
युगस्यादौ निमित्तं तन्महद्दिव्यं प्रचक्षते। यस्मिन् श्रूयते सत्यं ज्योतिर्ब्रह्म सनातनम्॥ अद्भुतं चाप्यचिन्त्यं च सर्वत्र समतां गतम्। अव्यक्तं कारणं सूक्ष्मं यत्तत् सदसदात्मकम्॥
