Q: If result of action is not in my hand, why should I work at all?
A: Action is to be performed for the sake of purification of mind.
Q: Why is my mind not in the present moment and how to bring my mind to the present moment 24×7?
A: In modern fast life too much Rajas (activity) could be the major reason for the existence of the habit of living in head. There could be too many tasks in, “To do” list made by your mind and it wants to jump from one task to another quickly. In this case your mind is always looking for, “What next?” and it may even treat a particular task as an obstacle that needs to be got rid of. Perhaps your mind wants to prove something to somebody or your mind is programmed from childhood to do too much work and not to rest etc. You need to do self inquiry to find out the real cause of this attitude applicable in your case, to slow down and to concentrate on doing one thing at a time .
While self inquiry is the fastest method of purification, Karma Yoga attitude is also very effective to mellow down Rajas.
