Mahabharata — Shanti Parva, Shloka 50
Nārāyaṇasya Guhya-nāmāni Niruktāni (Etymologies of Nārāyaṇa’s Secret Epithets) / नारायणस्य गुह्यनामानि निरुक्तानि
इन्द्रियैर्नियतैर्देही धाराभिरिव तर्प्यते । लोके विततमात्मानं लोकांक्षात्मनि पश्यति
indriyair niyatair dehī dhārābhir iva tarpyate | loke vitatam ātmānaṃ lokāṃś cātmani paśyati ||
那罗陀说道：当有情能摄伏诸根，使之受制，便得满足——如渴者遇雨流而得清凉。具知者观见自我（我、阿特曼）遍满一切众生，又见一切众生安住于自我之中；因此处世而内心充盈，不染不著。

Educational Q&A
Mastery over the senses brings genuine contentment, and true wisdom is the vision of the one Self pervading all beings and all beings resting in that Self—reducing craving, fear, and hostility.
In Śānti Parva’s instruction on peace and right living, Nārada delivers a teaching on inner discipline and spiritual insight, using the image of rain satisfying thirst to illustrate how sense-restraint culminates in serene, all-pervading Self-knowledge.
