The essential point in someone taking a pledge is tranquility. He wants to ensure that all his needs will be provided for and he will not have to worry. This idea is false since he has no guarantee he will be able to hold on to the money, what he would need or what may happen in his life. Even a greater point is the idea that if all his material needs were taken care of he would be satisfied and have peace of mind. Rabbenu Bachya teaches us " Material wealth is a lie, and betrays ignorance of what he wishes to attain for on the contrary it could be a major cause of worry and anxiety."
