अद्यश्वीना अवष्टब्धे

The word विजायते is understood here. The word अवष्टब्ध means 'imminent, near'. It is formed by अव + स्तंभ + क्त, the स् being changed to ष् by 8.3.68. Thus अद्य वा श्वो वा विजायते = अद्यश्वीना गौः \a cow likely to give birth to-day or to-morrow\. So also अद्यश्वीना वडवा ॥

Some do not read विजायते into the sutra, which then means \The word adyasvina is irregularly formed meaning imminent\. As अद्यश्वीनं मरणं 'imminent death'. अद्यश्वीनो वियोगः 'separation likely to take place to-day or tomorrow'.,
