अथ तु भुजगेन्द्ररूपः पुच्छेन मुखेन वा स गृह्णाति । मुखपुच्छान्तरसंस्थं स्थगयति कस्मान्न भगणार्धम् ॥ ५-०६ ॥
If being of the shape of a serpent he eclipses with his head or with his tail, how comes it that he does not hide one half of the heavens lying between his head and tail?
If, as some say, there be two Rāhus, when the moon is eclipsed by one of them at rising or setting how comes it we see the sun in the opposite point uneclipsed by the other Rāhu of equal motion?
The truth is that in her own eclipse, the moon enters the shadow of the earth, and in that of the sun, the solar disc. Hence, the lunar eclipse does not commence at the western limb nor the solar at the eastern limb.
Just as the shadow of a tree neither continues in the same direction nor of the same length, so changes the shadow of the earth, night after night owing to the revolution of the sun.
When the moon, whose course is always from west to east, is due opposite to the sun swerving neither much to the north nor to the south, she enters the shadow of the earth.
