Bhaktisiddhanta was known for his oratory and writing style as the "Acharya-Keshari". The term Acharya-Keshari is a combination of two words: Acharya, meaning "teacher", and Keshari, meaning "lion". Bhaktisiddhanta was a teacher who had a powerful voice and a strong presence. He was also a lion in the sense that he was courageous and never shied away from speaking his mind.
