This paper aims to illuminate the contribution of Pramukh Swami Maharaj in sustaining the Vedic philosophical principles propagated by Bhagavān Swaminarayan two centuries back. However, the period of two hundred years is enough to change the phenomenon of historical, social, religious and moral aspects. Consequently, these changes can also be perceived in the various philosophical principles which stand at two different and vast time zones. To address this dichotomy, this article first provides a critical note of the historical tradition of various Vedic philosophical branches and then examines the role and contribution of Pramukh Swami Maharaj in reviving Bhagavān Swaminarayan’s philosophical teachings. During his last years, Pramukh Swami inspired Mahāmahopādhyāya Bhadreshdas Swami to author the Prasthānatrayī Swaminarayan Bhāṣya, which, in Pramukh Swami’s words, encapsulates all the philosophical principles given by BhagavānSwaminarayan. Therefore, I will focus my research on how Pramukh Swami guided the writing of the Prasthānatrayī Swaminarayan Bhāṣya. Moreover, I will also evaluate its principles, whether they follow the principles of BhagavānSwaminarayan or not. The approach of investigation used in this paper will mainly be supported by the Vacanāmṛta (the authoritative text of the Swaminarayan faith), the biographies of the Guruparamparā (the spiritual lineage of BhagavānSwaminarayan), Pramukh Swami Maharaj’s diaries and the Prasthānatrayī Swaminarayan Bhāṣya.
