वैशेष्यात्तु तद्वादस्तद्वादः ॥ २२ ॥
vaiśeṣyāttu tadvādastadvādaḥ || 22 ||
vaiśeṣyāt—On account of the preponderance; tu—but; tadvādaḥ(-tadvādaḥ)—that special name.
22. But on account of the preponderance (of a particular element in them the gross elements), are so named (after it).
An objection is raised, if all the gross elements contain the three fine elements, then why such distinctions as “This is water,” “This is earth,” “This is fire”? The Sutra refutes this objection saying that as the fine elements are not found in equal proportion in each of the gross elements, they are named after that fine element which preponderates in their constitution. The repetition of “that special name” is to show that the chapter ends here.
