Love is the Key...

Love has the power to open the door of eternal life.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

Mystics of all ages have not been known for their miraculous powers or for the doctrines they have taught, but for the devotion they have shown throughout their lives. The Sufi in the East says to himself, Ishq Allah Ma'bud Allah, which means 'God is Love, God is the Beloved', in other words it is God who is Love, Lover, and Beloved. When we hear the stories of the miraculous powers of mystics, of their great insight into the hidden laws of nature, of the qualities which they manifested through their beautiful personalities, we realize that these have all come from one and the same source, whether one calls it devotion or whether one calls it love.

Love is that state of mind in which the consciousness of the lover is merged in that of the object of his love; it produces in the lover all the attributes of humanity, such as resignation, renunciation, humility, kindness, contentment, patience, virtue, calmness, gentleness, charity, faithfulness, bravery, by which the devotee becomes harmonized with the Absolute. As one of God's beloved, a path is opened for his heavenly journey: at the end he arrives at oneness with God, and his whole individuality is dissolved in the ocean of eternal bliss where even the conception of God and man disappears.
