When we do any action we believe we are doing it. Is it really true. Take the case of simple drinking of the coffee. Even to drink a cup of coffee millions and millions of actio should happen. Right from growing of coffee seeds, boiling water, rains, creation of earth, creation of universe. Each action of ours is dependant on zillions of actions. Zillions of chain of actions. So who is the doer ? Or is it just a happening ? And we probably are the observers ?
