"Lots of people are attracted to the teachings of the Buddha because the teachings are simple, direct and truthful. However, to claim that one is a student of the Buddha without the practice, is non-productive for the purpose of affectively changing one's behavior and actions.
Buddha's teachings are direct and hold no mysteries. It is a psychological, social and moral set of guidelines of how life ought to be lived in order to understand the difference between happiness and joy, and to learn the cause of your own suffering. Even if a person did not take to recite the Triple Jewel and the first Five Precepts of the householder, which is representative of an individual's commitment to themselves and to humankind in general, putting into practice the teachings of the Buddha is essential if one wishes to effectively learn what happiness is and how to be rather than have.
There are no mysteries presented in the teachings that are not provable nor are they complicated. Equally, with regard to the idea of rebirth, the branch of science known as Quantum Physics has, for nearly one hundred years, shown incontrovertible proof that there is no form of energy that can be created from nothing nor completely annihilated through physical destruction.
Continued existence of the consciousness of a sentient being is made a mystery only by religious dogma that keeps one from seeing or accepting the irrefutable truth. There are no mysteries accept those that are created by human perception and belief. Science has now identified that there is roughly a 3 to 4-minute window after the death of the body that consciousness can still be recorded."
