Whether we love humanity or not, we must realize that we are part of it. My future depends entirely on the future of humanity, and so I am compelled to take care of humanity. That is why being compassionate is actually in my own best interest. And a symptom of my own peace of mind is that I can share comfort with others around me.
Louis Pasteur, the great scientist, said "chance favours the prepared mind", which is a posh way of saying 'do your homework', but it's an excellent piece of advice.
There remain times when one can only endure. One lives on, one doesn't die, and the only thing that one can do, is to fill one's mind and time as far as possible with the concerns of other people. It doesn't bring immediate peace, but it brings the dawn nearer.
If I do not know reality, the unknown, how can I search for it? Surely it must come but I cannot go after it. If I go after it I am going after something which is the known, projected by me; by my own mind.
What is the source of sadness, but feebleness of the mind? What giveth it power but the want of reason? Rouse thyself to the combat, and she quitteth the field before thou strikest.
My own words are not the medicine, but a prescription; not the destination, but a map to help you reach it. When you get there, quiet your mind and close your mouth. Don't analyze the Tao. Strive instead to live it: silently, undividedly, with your whole harmonious being.
