Just for today, be aware of where you begin and end. Ask yourself if you could physically exist without the air. Or the sun. Or gravity. How about a plant-free planet? When you eat an apple, how do it’s molecules become you?
Where is the “I” that you refer to anyway? You say, “I have a headache,” even, “I have a body” but where is the “I” that has those things? There is a real sense, isn’t there, that there is a you that is looking out from inside your head and from behind your eyes?
In that case, might the real you be something eternal, permanent and just plain wonderful?
