In 1951, Bishop Nikolai came to St. Tikhons Seminary first as a professor and finally, with the death of the former Rector, Bishop Jonah, as Rector of the Seminary Here he lived out the last years of his life as an example of humility, as well as an elder to the monastics at St. Tikhons Monastery. To the students of the Seminary, the old Bishop was a loving father figure whom they would never forget. To the laity and faithful of the monastery parish, as well as all who came in contact with the Bishop, he was a hierarch in whom they saw manifest the grace of God. And to all, he was an example of humility. During his years as an educator at St. Tikhons Seminary Bishop Nikolai was seen to be a very unusual person in that his courses were profoundly simple, informal and very warm. His requirements were very basic: he taught, you learned, and he corrected.

Perhaps one of the most striking characteristics of his classes was that he taught solely in the English language, at a time when very few courses were taught in that language (and these usually by outside lecturers). This often caused friction with other faculty members, but Bishop Nikolai held fast to his position, for he knew the importance, for the seminarians, of hearing lectures in their native language. Indeed, without this use of English, much of the subtlety of his teachings would have been lost from memory. The use of English extended even to the monastery church, and on most occasions he would preach in that language. Often the parishioners would complain about this, but his answer would be: You have learned and heard enough. Its time for [the seminarians] to learn something.

Bishop Nikolais classes, sermons and conversations were always geared to his audience, whether they be students, professors, theologians or simple parishioners, and his vocabulary never extended itself beyond the comprehension of his hearers. For him, class could be any time. Anything said to him could be turned around and assigned a deeper meaning. He would always take examples from conversations in class, at the dinner table, or that which occurred as he walked about the grounds, and would always introduce examples from Holy Scripture, relating them to life at hand. For example, one day in class a student mentioned the fact that it was such a terribly dismal day because of the rain. Bishop Nikolai walked over to the window, looked out, and expounded on the further dimensions of rain, from Noah until the present time: What is rain? It is like Christ Who was also sent by the Father from Heaven to water a thirsty earth.

On Sunday, March 18, 1956, Bishop Nikolai fell asleep in the Lord. As related by the late Abbot Afanasy; The Bishop served the Holy Liturgy on Saturday, March 17. Everything was unusually beautiful. Following the service, he went to the monks dining room. After a short talk, with a low bow, three times he humbly muttered, Forgive me, brothers, as he was leaving. This was something special, for he never did that before.... He frequently spoke about wanting to be buried here at St. Tikhons Monastery; since he taught, prayed, and served God here. He had lived among the monks, and had said, 'It is more natural that I should be buried here. That Sunday morning, the late Fr. Vasily went down to Bishop Nikolais room at the Seminary and upon knocking at the door, received no answer. Opening it, he found the Bishop dead, stretched out on the floor in a kneeling position. In all probability, he had died between seven and eight that morning. The next day, a Memorial Service was served in the Monastery Church for the departed Hierarch by the Serbian Bishop Dionysius.

With deep humility and thankfulness for God's mercy; we fall down before our beloved Saint and Friend of God, crying out: Holy Hierarch Father Nikolai, pray unto God for us! (From The Tikhonaire for 1986 and 1988 quoted by orthodoxinfo.com)
