On 20 July 2012, in the presence of senior swamis in Ahmedabad, Pramukh Swami Maharaj revealed Keshavjivandas Swami (Mahant Swami) as his spiritual successor.

Following the death of Pramukh Swami Maharaj on 13 August 2016, Mahant Swami Maharaj became the 6th guru and president of BAPS.
In 1961, he was ordained as a swami by Yogiji Maharaj and named Keshavjivandas Swami.
Due to his appointment as the head (mahant) of the mandir in Mumbai, he became known as Mahant Swami.

He continues the legacy of the Aksharbrahma Gurus by visiting BAPS mandirs worldwide, guiding spiritual aspirants, initiating devotees, ordaining swamis, creating and sustaining mandirs, and encouraging the development of scriptures.

In his discourses, he mainly speaks on how one can attain God and peace through ridding one’s ego (nirmani), seeing divinity in all (divyabhav), not seeing, talking, or adapting any negative nature or behavior of others (no abhav-avgun), and keeping unity (samp).

In 2017, he performed the ground-breaking ceremony for shikharbaddha mandirs in Johannesburg, South Africa, and Sydney, Australia, and in April 2019, he performed the ground-breaking ceremony for a traditional stone temple in Abu Dhabi.
