Answer:
That religion is Buddhism.
Explanation:
According to Buddhism, many people cannot achieve happiness because of the belief that they must hold on to their worldy goods, their beliefs and their feelings to be happy. On the other hand, Buddhism affirms that happiness cannot come from things external to the person, or from temporary matters such as their beliefs and feelings because all of those change throughout their lives. According to Buddhism, attachment to worldy goods and ego only bring sadness and suffering. This does not mean that we do not fight to obtain wordly goods or to form each one the best that we can, but that we do not pretend that our happiness depends on our reaching those material or image goals that we want to transmit to ourselves and to society.
