मच्चित्ता मद्गतप्राणा बोधयन्तः परस्परम् | कथयन्तश्च मां नित्यं तुष्यन्ति च रमन्ति च
mac-cittā mad-gata-prāṇā bodhayantaḥ parasparam | kathayantaś ca māṃ nityaṃ tuṣyanti ca ramanti ca
With mind fixed on Me, with life dedicated to Me, instructing each other and speaking of Me, they are always satisfied and rejoice.
The description of the devotional community. Mat-cittāḥ — whose mind (citta) is on Me — complete absorption. Mat-gata-prāṇāḥ — whose life (prāṇa) has gone to Me — total dedication.
Bodhayantaḥ parasparam — instructing each other — the spiritual saṅga, association of devotees. Kathayantaḥ — speaking, narrating — about the Lord.
Tuṣyanti — satisfied — and ramanti — they delight — are the emotional states of the devotee. The saṅkīrtana (congregational chanting) is the natural expression of this community.
