A 1989 document generally known as "Aspects of Christian meditation" set forth the position of the Holy See with respect to the differences between Christian and eastern styles of meditation. The document, issued as a letter to all Catholic bishops, stresses the differences between Christian and eastern meditative approaches. It warns of the dangers of attempting to mix Christian meditation with eastern approaches since that could be both confusing and misleading, and may result in the loss of the essential Christocentric nature of Christian meditation. The letter warned that euphoric states obtained through Eastern meditation should not be confused with prayer or assumed to be signs of the presence of God, a state that should always result in loving service to others. Without these truths, the letter said, meditation, which should be a "flight from the self", can degenerate into a form of self-absorption.
