Commentary

The same substitution takes place when the affix अस्ताति follows.
That is पुर् for पूर्व, अध् for अधर and अव् for अवर ॥ This sutra indicates by implication that the affix अस्ताति 5.3.27 is not debarred by अस् after these words. Thus पुरस्तात् or अधस्तात् or अवस्तात् वसति or आगतः or रमणीयम् ॥
