The placing of the epitaphios (plashchanitsa) on the tomb of Christ.
“A Christian must be courteous to all. His words and deeds should breath with the grace of the Holy Spirit, which abides in his soul, so that in this way he might glorify the name of God. He who regulates all of his speech also regulates all of his actions. He who keeps watch over the words he is about say also keeps watch over the deeds he intends to do, and he never goes out of the bounds good and benevolent conduct. The graceful speech of a Christian is characterized by delicateness and politeness. This fact, born of love, produces peace and joy. On the other hand, boorishness gives birth to hatred, enmity, affliction, competitiveness, disorder and wars.”
“How mistaken are those people who seek happiness outside of themselves, in foreign lands and journeys, in riches and glory, in great possessions and pleasures, in diversions and vain things, which have a bitter end! In the same thing to construct the tower of happiness outside of ourselves as it is to build a house in a place that is consistently shaken by earthquakes. Happiness is found within ourselves, and blessed is the man who has understood this. Happiness is a pure heart, for such a heart becomes the throne of God. Thus says Christ of those who have pure hearts: “I will visit them, and will walk in them, and I will be a God to them, and they will be my people.” (II Cor. 6:16) What can be lacking to them? Nothing, nothing at all! For they have the greatest good in their hearts: God Himself!” - St. Nektarios of Aegina, The Path to Happiness
