The high proficiency in Vedas, Upanishads, Shastras, etc. , the command over languages like Sanskrit, English, Tamil and Hindi and his tireless pursuit to elevate the society intellectually, spiritually and to maintain the age old Indian Culture in the form of religious discourses on various topics like Ramayana, Mahabharatha,Narayaneeyeam,SkandaPuranam,Srimad Bhagavatham etc is appreciable.
He has been blessed by the Acharyas of Sringeri and Kanchi.

His frequent definitions in English and the extremely pertinent quotations adds dignity to his discourses.

His explanations are full of depth, drawn from his own profound learning and that of the great interpreters of Bhagavatham.

Being well-educated and having worked with various organisations and in various capacities, Shri Sundar Kumar is conversant with the modern gizmos and the topical issues. Hence his appropriate analogies explain as well as entertain.

The special appeal of Sri Sundar Kumar is his deep bhakthi and self-effacing humility. His tone does not command or preach.
