His original works include the highly regarded book, the Vedānta-darśanam bhāgavata bhāṣyopetam, his translation-cum-commentaries of the Sat Sandarbhas, and his transliterations of Śrī-caitanya-bhāgavata, Śrī-caitanya-caritāmṛta and Śrī-caitanya-maṅgala.
Jonathan Edelmann at the University of Florida has called Śāstrī "arguably the most prolific and well-educated Gauḍīya Vaiṣṇava “insider” scholar of the twentieth century" and "a voice distinct from the more well known Gaudīya-Maṭha and ISKCON".
[2] Paṇḍita Bābā chose his only veṣa disciple Śrī Vinod Vihārī Goswāmī as Phaṇīndra Nāth’s teacher.
Later, ordered by his guru, Śrī Haridāsa then went to Benares where he studied Indian philosophy for twelve years.
His purpose was to make the works of Gaudiya Vaisnava acharyas, mainly Jiva Goswami's, which were primarily in Sanskrit, accessible to the public.
Edelmann notes, "many academic scholars of the Gauḍīya Vaiṣṇava tradition have used Haridāsa Śāstrī published editions of the Gosvāmin’s literature".
Sri Haridas Shastri addressed this key gap in the Gauḍīyā Vaiṣṇava literature, by writing and publishing his book Vedānta-darśanam.
To ensure that the services that he started continued in his absence, he established Śrī Haridās Śāstrī Cow Institute with a board of trustees.
