Try to be mindful, and let things take their natural course. Then your mind will become still in any surroundings, like a clear forest pool. All kinds of wonderful, rare animals will come to drink at the pool, and you will clearly see the nature of all things. You will see many strange and wonderful things come and go, but you will be still. This is the happiness of the Buddha.
There may be a million microbes of misery floating about us. Never mind! They dare not approach us, they have no power to get a hold on us, until the mind is weakened.
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.
