Sūta said:: The sun that has seven horses has an upper and a lower position by turns. When the sun is in his northern transit and when the moon, on the full moon nights, appears quickly because its position, is above, but the rays are not very clear, the moon (?) then is in the southern orbit that is lower. The sun. covered by the line of the earth on Full moon and New Moon days is seen, at the usual time, but it sets quickly. Hence on the New-Moon day the moon is in the northern orbit. It is invariably not seen, in the southern path on account of the movement of the planets and because it is enveloped by the shadow of the sun. On the equinotical days the sun and the moon rise and set simultaneously.[2]
