Caring – to care – in all of its forms and in just about any culture and language one can imagine - has existed as just so much normalcy in the day-to-day of life. It appears to be something worthy of our consideration, our time, our efforts & most, if not all, of our resources.
The importance of sleep in daily life is that it is considered a basic necessity of life, as important to our health and well-being as air, food and water.
One day the Buddha was sitting in the wood with thirty or forty monks. They had an excellent lunch and they were enjoying the company of each other. There was a farmer passing by and the farmer was very unhappy. He asked the Buddha and the monks whether they had seen his cows passing by. The Buddha said they had not seen any cows passing by.
