How do I know the path that I choose to take is the right one when there are so many different paths that I can take?
When doubt comes, then know for sure it is the right one. Generally, we doubt only that which is true. All that is good, we doubt. If someone asks if you are happy you say, “Well, I am not sure.” But you are so definite about your unhappiness, right? Similarly if someone tells you that they love you so much, you will say, “Really?” And if someone says, “I hate you,” you never say, “Really?”
So most of the time, our doubts are about something that is positive. So when you are on a path that you like, the doubt whether this is the right path or not will come.
