I feel perfectly capable of imagining impressive effects coming from Buddhist Tantric practices, which are nothing but a process of mental re-education. But neither Buddhism nor any other Eastern school can convince me of the nonsense of denying reality, no matter how wonderful effects they promise by doing so. I understand the dangers of valuing on error, I understand, above all, the need to break with earthly ties; but my mind violently rejects considering myself a nothing in essence, wrapped in a nothingness devoid of any foundation: zeros and more zeros, and never anything. No! There are illusions, and I can distinguish them because there is also something non-illusory. There is the mind and the products of the mind, just as there is an external reality that differs from them. I am sorry, I am sorry, but I cannot accept as identical phenomena an imaginary punch in the face and a real punch in the face—and I can, what a novelty!, prove what I say.
