When studying in the first or second class of a High School, Hariprasanna saw Ramakrishna at Dewan Govinda Mukherji's house.

'[4] He was rebuked by his mother and elder sister for the transgression and could not go to see Ramakrishna for a long time, who sent Sarat to bring him along.

Ramakrishna made him enter into a deep meditation and gave him intimate knowledge on various facets of spiritual lives.

wrote Swami Vivekananda in a letter to Sister Nivedita on 20 June 1897, in the context of Hariprasanna's renunciation.

Vijanananda made Allahabad his permanent place, and he established a centre of Ramakrishna Mission.

During his last few years he travelled extensively and visited many centres of Ramakrishna Math, including those of Rangoon and Colombo.

On 14 January 1938, Vijanananda performed the dedication of the temple and the consecration of the marble image of Sri Ramakrishna.

There is a dormitory named, in his honour, Vijnanananda Dham in Ramakrishna Mission Vidyapith, Deoghar and also in Ramkrishna Mission Vidyapith, Purulia Swami Vijanananda constructed the major buildings of Belur Math, as well as the embankment on the Ganges in front of the main temple.

Vivekananda entrusted him with the responsibility of planning a big memorial temple dedicated to Ramakrishna, giving him specific instructions.

The Swami, in consultation with a noted European architect of Calcutta, prepared a design of the proposed temple, which was approved by Vivekananda.

Thirty years after Vivekananda's death, the temple plan was revived when an unexpected financial help was received from some devoted American students.

The foundation stone of the temple was laid by Vijanananda, then Vice President of Ramakrishna Math and Mission, in July 1935.

Hariprasanna Maharaj also established the Ramakrishna Math and Mission in Allahabad and trained many novice monks there.

He also supervised the construction of some of the buildings of Ramakrishna Mission Home of Service in Benaras as well as the Swami Vivekananda temple in Belur Math.

[3] While studying in Patna, Hariprasanna had a vision of Ramakrishna, which took place on the day of the latter's passing away in Cossipore in Calcutta in 1886.
