Once, he came to know about Shree Shree Ma Anandamayee Vidyapeeth which was at Almora at that time. This institution is a residential school for young boys imparting traditional Indian education to them and training them for living as brahmacharis in the ancient Gurukul sym. As he learned about this school, without delay, Chattopadhyayaji reached Almora with the two sons of his for their admission in the Vidyapeeth. The elder son, Naba Kumar was ten and the younger one, Tapan Kumar, was just eight years of age. They became inmates of the Brahmacharya Ashram at this tender age and by Ma’s Grace, grew up as well trained brahmacharis.

In January, 1947, when the Savitri Mahayajña was begun in Varanasi, these two brothers were selected in the role of hota (as active participants in the puja ceremony) along with some others Brahmin boys. After the ritual of Purnōhuti (final offering of oblation) which took place in January, 1950, they went back to the Vidyapeeth. In due course of time, when Tapan Kumar passed the Matriculation Examination, Shree Durga Singhji, Maharaja of Baghat, Solan, a great devotes of Shree Shree Ma, offered to bear all expenses for his further education. With his financial help, Brahmachari Tapan passed the M. A. Examination from the Delhi University. He was a talented student and procured brilliant results.

In 1961, Shree Ma had a kheyal that the three young Brahmacharis of the Ashram, Br. Kusum, Br. Bharat and Br. Tapan be initiated into Naishthika Brahmacharya. Accordingly, they were given this special diksha in Baghat House, Haridwar, on the bank of the Ganga. Kusum, Bharat and Tapan were respectively named as Nirvanananda, Bhaskarananda and Nirmalananda. For three yours, they observed the strict rules of their new life, going through an elaborate process of self purification and were fully ordained as Naishthika Brahanacharis, shining with the purity and splendour of tapasya. The three were acknowledged in the Ashram as priests invested with special rights to perform all religious rituals.

In the year 1970, the Maharirvana of Shree Swami Muktananda Giriji (revered mother of Shree Ma) took place. She had been the Diksha Guru of Shree Anandamayee Sangha. Now these three Brahmacharis were unanimously elected in the role of Diksha Guru of the Sangha in place of Didima (Shree Giriji). lnumerable devotees received mantra diksha and Shree Ma’s blessings from them.

Br. Nirmalanandaji, fondly called Nirmalda, was given the responsibility of conducting the satsing sessions held by Shree Anandamayee Sangha. He was a very good orator and was able to enthrall audiences by his erudite and captivating speech. He was appreciated and liked by the sadhus and Mahatmas and was on good with them.

He also performed many times the Bhagavata Parayana in the role of the Pathak and delivered scholarly and charming discourses.

He occupied a prominent place in the Ashram also as a Pujak, the main Priest performing and organising puja on special occasions. He efficiently fulfilled the duties and responsibilities as Secretary on the Managing Committee of many Ashram Branches. He held revered Panuda in great esteem since Panuda had been his teacher in the Vidyapeeth. The Publication Division of Shree Shree Anandamayee Sangha was under Ninnalanandaji’s care and guidance He was also a gifted writer and contributed valuable articles for the Ashram magazine Amrit Varta.

In 1982, during the last days of Shree Ma’s lila on earth, Nirmalanandaji was present in the Kankhal Ashram. After Shree Ma entered into the Avyaktam, he organised the rituals with dedication and thoughtfulness.

A few years after Shree Ma’s Mahanirvana, Nirmalanandaji took sannyasa and came to be know as Swami Nirmalananda Giri.

Around the year 2000, some devotes from Chandan Nagar implored Nirmalanandaji to come and stay in Matri Dham, Chandan Nagar and delight the local devotees by narrating spiritually inspiring stories of Shree Ma’s divine life. Yielding to their request, he went to live permanently in the Chandan Nagar Ashram.

For some years, Swamiji was having debility and health complaints due to age. On 13th February, 2017 he left for the Abode of the Eternal to rest in peace at the Lotus feet of Shree Ma. Ma. Swamiji will always be remembered as a dear child of Shree Ma, a veteran Jñanayogi and Karmayogi of Shree Ma’s Ashram,
