You do action through your body, mind and speech. Whatever you do, you receive back.
Remember, you are a highly complex and dynamic machine. The challenge is that you are not only a machine but at the same time its operator too.
Your conscious-awareness and continuous-calibration with your deep-inner-self is the primary determinant if the output is joy and prosperity, or the misery and misfortune!
Oneness is a joy. Divide is a pain.
Therefore, the scripture ('Shastra') alone is your guide in determining what should be done and what should not be done.
Non-violence, truthfulness, the absence of anger, self-sacrifice, peace, not blaming others, compassion, no attachment to sensory pleasures, modesty, and steady state of mind are the way to the prosperity.
Sometimes, life gives us test! The path to future becomes too foggy; it does not remain obvious what is wrong or right? Circumstances demand some hard decisions to be made; choices, that not only test your true purpose but would be questioned by the history too.
If you are doubtful, double-minded, or have any other inner conflict, you may not achieve the real success. To accomplish any significant in the world, you need to be one with your own- self. Your actions and your attention should lead you towards that one goal you have decided for yourself. Like a ‘KarmaYogi’, once determined, your actions should follow your mind harmoniously, and your mind should follow your cause with complete devotion!
