why my brain is not enough to show me right way in m life?

It is due to inertia. It is called tamasic quality. It is a state of ignorance or inactivity, It blocks your real vision. That is why you are not able to go in right direction. When you want to go in right direction, your fate takes you in negative or left direction. It is really unfortunate.

Please consult a good astrologer with your horoscope. He will provide a good solution for this.

Does the stone sink when you throw it into the water? Or does the water simply drag it down on its own accord.

*hits blunt*

Just think about that for a second bud.
