Unless you have made a clear decision to turn your back on samsara, then however many prayers you recite, however much you meditate, however many years you remain in retreat, it will all be in vain. You may have a long life, but it will be without essence. You may accumulate great wealth, but it will be meaningless. The only thing that is really worth doing is to get steadily closer to enlightenment and further away from samsara. Think about it carefully.
