Dhīra means who is not disturbed. He's called dhīra. And there are others who are called adhīra. Adhīra means those who are disturbed. So those who are in the material world, they are always disturbed. And those who are on the spiritual platform, they are dhīra. Dhīrādhīra. About the Gosvāmīs it is said:
- kṛṣṇotkīrtana-gāna-nartana-parau premāmṛtāmbho-nidhī
- dhīrādhīra-jana-priyau priya-karau nirmatsarau pūjitau
- śrī-caitanya-kṛpā-bharau bhuvi bhuvo bhārāvahantārakau
- vande rūpa-sanātanau raghu-yugau śrī-jīva-gopālakau
So one who is in the transcendental position, he's dhīra. One poet, poet Kālidāsa, he has described, dhīra means: "Even in the presence of provocation, one who is not disturbed, he's called dhīra."
