CC Madhya 6.100
- pratiyuge karena kṛṣṇa yuga-avatāra
- tarka-niṣṭha hṛdaya tomāra nāhika vicāra
prati-yuge—in every age or millennium; karena—makes; kṛṣṇa—Lord Kṛṣṇa; yuga-avatāra—incarnation for the age; tarka-niṣṭha—hardened by argument; hṛdaya—heart; tomāra—your; nāhika—there is not; vicāra—consideration.
Gopīnātha Ācārya continued, “There is certainly an incarnation in every age, and such an incarnation is called the yuga-avatāra. But your heart has become so hardened by logic and argument that you cannot consider all these facts.
