In this school He would simply explain Kṛṣṇa, even in readings of grammar. Śrīla Jīva Gosvāmī, in order to please the Lord, later composed a grammar in Sanskrit, in which all the rules of grammar were explained with examples that used the holy names of the Lord. This grammar is still current. It is known as Hari-nāmāmṛta-vyākaraṇa and is prescribed in the syllabus of schools in Bengal.
During this time a great Kashmir scholar named Keśava Kāśmīrī came to Navadvīpa to hold discussions on the śāstras. The Kashmir paṇḍita was a champion scholar, and he had traveled to all places of learning in India. Finally he came to Navadvīpa to contest the learned paṇḍitas there. The paṇḍitas of Navadvīpa decided to match Nimāi Paṇḍita (Lord Caitanya) with the Kashmir paṇḍita, thinking that if Nimāi Paṇḍita were defeated, they would have another chance to debate with the scholar, for Nimāi Paṇḍita was only a boy.
