Be at peace with your own soul, then heaven and earth will be at peace with you. Enter eagerly into the treasure house that is within you, you will see the things that are in heaven; for there is but one single entry to them both. The ladder that leads to the Kingdom is hidden within your soul... dive into yourself, and in your soul, you will discover the stairs by which to ascend.
Saint Issac Nineveh, 7th century
