Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Moksha-Sanyasa Yoga Chapter 18, Verse 18.54.
Sanskrit
ब्रह्मभूतः प्रसन्नात्मा न शोचति न काङ्क्षति । समः सर्वेषु भूतेषु मद्भक्तिं लभते पराम् ॥ १८.५४ ॥
Hindi
फिर वह सच्चिदानन्दधन ब्रह्म में एकीभाव से स्थित, प्रसन्न मन वाला योगी न तो किसी के लिये शोक करता है और न किसी की आकाँक्षा ही करता है । ऐसा समस्त प्राणियों में सम भाव वाला योगी मेरी परा भक्त्ति को प्राप्त हो जाता है ।
English
This being becomes one with God (or the Supreme Brahman), and his soul experiences true joy, peace and bliss. He no longer feels any desire for material things nor does he recognize any grief. He extends his love to all creation in this world and shows supreme love and unfailing devotion to Me, the Lord of all.
