In this external world, which is full of finite things, it is impossible to see and find the Infinite. The Infinite must be sought in that alone which is infinite, and the only thing infinite about us is that which is within us, our own soul. Neither the body, nor the mind, nor even our thoughts, nor the world we see around us, is infinite.
When an idea is just rising on the horizon, the soul's temperature with respect to it is usually very cold. Only gradually does the idea develop its warmth, and it is hottest (which is to say, exerting its greatest influence) when belief in the idea is already once again in decline.
Intense, unexpected suffering passes more quickly than suffering that is apparently bearable; the latter goes on for years and, without our noticing, eats away at our souls, until, one day, we are no longer able to free ourselves from the bitterness and it stays with us for the rest of our lives.
