I should like to meet a philosopher like Nietzsche somewhere in a train or a steamer, and to spend the whole night talking to him. I consider his philosophy won't last long, however. It's more showy than convincing.
Spirituality automatically leads to humility. When a flower develops into a fruit, the petals drop off on its own. When one becomes spiritual, the ego vanishes gradually on its own. A tree laden with fruits always bends low. Humility is a sign of greatness.
Remember your contemporaries who have passed away and were your age. Remember the honors and fame they earned, the high posts they held, and the beautiful bodies they possessed. Today all of them are turned to dust. They have left orphans and widows behind them, their wealth is being wasted, and their houses turned into ruins.
No sign of them is left today, and they lie in dark holes underneath the earth.
Picture their faces before your mind's eye and ponder.
The instruction we find in books is like fire. We fetch it from our neighbours, kindle it at home, communicate it to others, and it becomes the property of all.
