साधवो हृदयं मह्यं साधूनां हृदयं त्वहम् ।
मदन्यत्ते न जानन्ति नाहं तेभ्यो मनागपि ॥
sādhavo hṛdayaṁ mahyaṁ sādhūnāṁ hṛdayaṁ tv aham |
mad-anyat te na jānanti nāhaṁ tebhyo manāg api ||
(Śrīmad Bhāgavatam: 9.4.68; cited in Paramātma Sandarbha: 93, Prīti Sandarbha: 65; Caitanya-caritāmṛta: 1.1.62)
[Viṣṇu to Durvāsā:] “Sādhus are my heart, and I am the sādhus’ heart. They do not know anyone other than me, and I do not know anyone other than them at all.”
