Being ardent about cultural activities from childhood, Harinath would keep abreast with the current ongoing cultural programs in the city. Harinath would enquire about any competitions for elocution and monoacting, and would enthusiastically participate. He always won prizes and applause from the organisers and audience. One of the major praiseworthy wins for him was Diksuchi elocution. Diksuchi elocution was conducted by Telugu morning newspaper, at various levels, participants being from both the Telugu states (Telangana and Andhra Pradesh). Harinath succeeded in all the rounds and in the finals, he stood first from both the states and won a cash prize. In Ramakrishna Mutt, Harinath played various roles in English plays, in one play he donned 3 roles simultaneously. Swami Paramatmananda, the president of Ramakrishna Mutt (at that time) was impressed by Harinath’s sincere efforts and involvement in making the play successful. He personally used to congratulate Harinath for his good acting and team spirit.
