“Aristotle taught that there was an immovable ‘entelechy’ in the universe that moves everything and the thought was its main attribute. I am also convinced that the whole universe is unified in both material and spiritual sense. Out there in the universe there is a nucleus that gives us all the power, all the inspiration; it draws us to itself eternally, I feel its mightiness and values it transmits throughout the universe; thus keeping it in harmony. I have not breached the secret of that core, still I am aware of its existence, and when wanting to give it any material attribute I imagine LIGHT, and when trying to conceive it spiritually I imagine BEAUTY and COMPASSION. The one who carries that belief inside feels strong, finds joy in his work, for he experiences himself as a single tone in the universal harmony.”
