I know one day everyone will die but I just wonder is it God who decides how long we can stay here? my mother is almost 100. I just want a long life.
According to the teachings of Paramhansa Yogananda, each individual’s life span is determined by karma. Your past karma, plus the karma that you generate from now on, plus God’s grace, will determine the span of your life.
Although there is nothing we can do to guarantee any particular life span, your best plan is to live, from this point onward, a healthy life on all levels: physical, mental, and spiritual. Also, do your best to attune yourself to God’s will in all that you do; for that, the practice of daily meditation is essential. Then you will have done everything in your power; the rest is up to God and your karma.
