Rudra-Śiva: Names, Two Natures, and the Logic of Epithets (रुद्रनाम-बहुरूपत्व-प्रकरणम्)
फलमूलाशनं वायुराप: शैवलभक्षणम् | ऋषीणां नियमा होते यैर्जयन्त्यजितां गतिम्
phalamūlāśanaṃ vāyur āpaḥ śaivalabhakṣaṇam | ṛṣīṇāṃ niyamā hote yair jayanty ajitāṃ gatim ||
圣者摩醯湿伐罗说道：以果与根为食，以风为资生，只饮清水，乃至食水中之草木——此皆诸仙（ṛṣi）所守之戒行。凭此节制与苦行，他们得以征服本难征服的生死流转之途，以自制与精进驾驭那艰险之道。

Educational Q&A
The verse teaches that rigorous self-restraint and austere observances (niyamas)—especially disciplined control of food and bodily needs—are powerful means by which sages overcome the hardest spiritual obstacles and master the difficult path of existence.
Maheśvara is describing the kinds of ascetic practices followed by ṛṣis—living on fruits and roots, subsisting on air, taking only water, or eating algae—as exemplary disciplines that enable spiritual conquest of an otherwise unconquerable 'gati' (course/goal).
