Surya Siddhanta
त्रिपादम् अमृतम् गुह्यम् पादो +अयम् प्रकटो +अभवत् । सो +अहङ्कारम् जगत्सृष्ट्यै ब्रह्माणम् असृजत् प्रभुः॥
Three quarters of his creative potency are hidden [in the blissful spiritual kingdom]—only the material world is manifest as the fourth quarter. This manifestation has created Brahmä, the supreme creator, as the principle of consciousness (ahankära) for creating the universe.
