Enroute to my office is an blacksmith shop. The owner’s dog is always on a leash and tied to an iron pole. He sits majestically and watches the mad traffic. Quietly and peacefully. Never irritated about the fact that he is permanently tied to the pole.
Adjoining this is a chicken shop with many cages filled with birds. Some of them are busy enjoying their feed, whilst some of them cock their head at the passerby. They are completely unmindful of their future, even though the table opposite is filled with entrails.
1. Observe, wander in the mind, do not think you are tied (from the dog)
2. Enjoy the now, do not worry about the future. (from the chickens)
