गदायुद्धप्रतिज्ञा — The Vow and Terms of the Mace Duel
क्रियाभ्युपायैर्बहुभि्मायामप्सु प्रयोज्य च

“By employing many practical means and stratagems, and by deploying illusion upon the waters as well…”
वायुदेव उवाच
The line highlights that outcomes in conflict are often pursued through multiple expedients, including deceptive stratagems; it implicitly raises the ethical tension in the Mahābhārata between effective means (upāya) and righteous conduct (dharma).
Vāyudeva is describing (or introducing) the use of many action-based methods and a form of māyā—an illusory or deceptive device—applied in connection with water, as part of a broader account of tactics or extraordinary means.
