Higher Self: Fire
Like the Sun, fire also symbolizes the prolonged state of Presence. Fire represents the idea of transforming suffering. The fuel of friction and negativity ignites the Light of Presence, a higher state of consciousness.
Ouspensky: If a man gives way to all his desires, or panders to them, there will be no inner struggle in him, no 'friction,' no fire. But if, for the sake of attaining a definite aim, he struggles with desires that hinder him, he will then create a fire which will gradually transform his inner world into a single whole.
Rumi (13th c. Sufi mystic and poet): Very few can sit down in the middle of the fire itself.
Nicephorus the Solitary, Philokalia (Greek Orthodox Christian text): You who seek to feel the Divine fire in your heart, who wish to know and to receive the kingdom of heaven existing within you, come,and I will impart to you the science of eternal heavenly life.
Liu Yiming (18th c. Taoist master): The firing process spoken of in the alchemical classics and writings of the Taoist masters, is a metaphorfor the order of practical spiritual work.
Chao Pi Chen (20th c. Taoist Master): The six stages of purification by fire …are in sequence and should never be mixed up; only then can it produce the Golden Elixir.
Gnostic Gospel of Thomas (Christian text): Jesus said, I have cast fire upon the world, and see, I am guarding it until it blazes.
