If I equate your body to a mango I will equate the kundalini to the seed inside. A mango fruit does not achieve its ultimate, if you just eat the fruit and destroy the seed. The fruit realizes itself only when the seed is able to give more fruits. In the same way, your body has two components, the kundalini and your body. Just living with a little money, comfort and ending your life is like eating the mango fruit. But, that will not to lead to realization. The fruit itself realizes its purpose of existence only when the seeds start giving more fruits.
