The source of all the material comes from nothingness, illusion is working more on things you can prove. Thats the principle, the essence of life, it is actually an illusion, not immaterial. Thats worth pursuing. So illusion is not nothing. In a way, that is the truth. – Ang Lee
No human being is constituted to know the truth, the whole truth, and nothing but the truth and even the best of men must be content with fragments, with partial glimpses, never the full fruition. – William Osler
