मयितेति वा शमः ।विषयसुखेष्वसङ्गतया शान्तः, 'निष्कलं निष्क्रियं शान्तम्' इति श्रुतेः ।प्रलये नितरां तत्रैव तिष्ठन्ति भूतानीति निष्ठा ।समस्ताविद्यानिवृत्तिः शान्तिः ।सा ब्रह्मैव परमुत्कृष्टमयनं स्थानं पुनरावृत्तिशङ्कारहितमिति परायणम् ।पुंलिङ्गपक्षे बहुव्रीहिः ॥
In plain words
Or else, Śama denotes one who remains serene through utter detachment from sensory joys, as scripture declares: 'Partless, inactive, tranquil.' He is Niṣṭhā, the ultimate ground, because all created beings rest securely within him during the cosmic dissolution. Śānti is the absolute eradication of all ignorance. That very peace is Brahman itself—the supreme and flawless abode, entirely free from the fear of ever returning to worldly existence, and therefore he is Parāyaṇa, the ultimate refuge. When interpreted in the masculine gender, it forms a bahuvrihi compound.
Close to the Sanskrit
Or Śama means one who is tranquil due to non-attachment to sensory pleasures, as the shruti says 'Partless, inactive, tranquil.' Niṣṭhā is because beings truly reside precisely there during dissolution. Śānti is the complete cessation of all ignorance. That very peace is Brahman, the supreme excellent destination and abode, devoid of any fear of return, hence Parāyaṇa. In the masculine gender aspect, it is a bahuvrihi compound.
