Each of us must learn to work not just for one self, one's own family or one's nation, but for the benefit of all humankind. Universal responsibility is the key to human survival. It is the best foundation for world peace.
Love moderately. Long love doth so. Too swift arrives as tardy as too slow. *Love each other in moderation. That is the key to long-lasting love. Too fast is as bad as too slow.*
Scientists are coming to recognise the effects of the mind on physical health. The sense of relaxation associated with inner peace involves not only being physically at ease. If you are nagged by worry or seething with anger, you’re not really relaxed. The key to relaxation is peace of mind. The relaxation gained from alcohol, drugs or just listening to music may seem attractive, but it doesn’t last.
Surely we cannot take an open question like the supernatural and shut it with a bang, turning the key of the madhouse on all the mystics of history. You cannot take the region of the unknown and calmly say that, though you know nothing about it, you know all the gates are locked. We do not know enough about the unknown to know that it is unknowable.
Thought is a key to all treasures; the miser's gains are ours without his cares. Thus I have soared above this world, where my enjoyments have been intellectual joys.
The mind is key. If anything should be considered a god, so to speak, it is the mind, not money. A healthy positive mind is the utmost priority.

I find it hard to imagine how a person with great wealth, bad health, no friends, and no peace of mind could feel even slightly happy.
