Ut Unum Sint

Russian Orthodox priest Father Alexander Gumanovsky, quoted in The Rosary and Orthodoxy:

"I forgot to give you a piece of advice vital for salvation. Say the '0 Hail, Mother of God and Virgin' one hundred and fifty times, and this prayer will lead you on the way to salvation. This rule was given by the Mother of God herself in about the eighth century, and at one time all Christians fulfilled it. We Orthodox have forgotten about it, and St. Seraphim has reminded me of this Rule. In my hands I have a hand-written book from the cell of St. Seraphim, containing a description of the many miracles which took place through praying to the Mother of God and especially through saying one hundred and fifty times the 'O Hail, Mother of God and Virgin.' If, being unaccustomed to it, it is difficult to master one hundred and fifty repetitions daily, say it fifty times at first. After every ten repetitions say the 'Our Father' once and 'Open unto us the doors of thy loving-kindness' Whomever he spoke to about this miracle-working Rule remained grateful to him…"
