Surya Siddhanta
मेषादौ देवभागस्थे देवानाम् याति दर्शनम्। असुराणाम् तुलादौ तु सूर्यस् तद्भागसञ्चरः॥
In the half-revolution beginning with Aries, the sun, being in the hemisphere of the gods, is visible to the gods : but while in that beginning with Libra, he is visible to the demons, moving in their hemisphere.
