Dhīra means sober, and adhīra means just the opposite, debauchers. So they were dear to both classes of men. This is Kṛṣṇa-kīrtana, is so nice. It is dear to all classes of men. Dhīrādhīra-jana-priyau priya-karau nirmatsarau pūjitau. Because they are not envious. This Kṛṣṇa consciousness movement is not meant for a particular class of men. It is meant for everyone. So... And what was their other qualification? Śrī-caitanya-kṛpā-bharau... Dhīrādhīra-jana-priya-priyakarau nirmatsarau pūjitau, śrī-caitanya-kṛpā-bharau... They're very dear servitors of Lord Caitanya Mahāprabhu for delivering the fallen souls of this world. And we have to offer our respectful obeisances to the six Gosvāmīs, vande rūpa-sanātanau raghu-yugau srī-jīva-gopālakau.
Then their next qualification, next engagement was nana-śāstra-vicaraṇaika-nipunau. Śāstra, all kinds of Vedic literature. Śāstra means which governs. The Vedic literature governs. There is a verbal root which is called śāst. Śāst means to rule. The ruling, there are three kinds of ruling. One ruling is śāstra, law codes. Just like every civilized country is ruled by the laws of the state, and the statute book which contains all the rules, that is called law books. That is also śāstra. That is śāstra. And then another śāsdhātu is śastra. Śastra means weapons, that like guns, swords. Śāstra and śastra. So there are two sections of people: those who are civilized, they are ruled by the śāstra, by the law codes, and those who are law-breakers, they are ruled by the śastra, weapons. Both things are required, śāstra and śastra. And sasam, sasam means government. The government has two department—criminal and civil. Civil department is controlled by the śāstra, law codes, and the criminal department is governed by the śastra, weapons. So this is the rule from time immemorial. Both things are required. Sometimes violence required, police force required for the unruly persons. They'll not care for the śāstra, don't care for śāstra, but you care for the śastra. So two things are there.
