Bhagavad Gita 10.9

With minds concentrated on Me, with lives absorbed in Me, and enlightening one another, they ever feel content and happy.

मच्चित्ता मद्गतप्राणा बोधयन्तः परस्परम्।
कथयन्तश्च मां नित्यं तुष्यन्ति च रमन्ति च॥

maccittā madgataprāṇā bodhayantaḥ parasparam|
kathayantaśca māṃ nityaṃ tuṣyanti ca ramanti ca||
