Prescribed Duty - In Gita Verse 3.8 Perform your prescribed duty, for doing so is better than not working. One cannot even maintain one’s physical body without work.
Krishna now very specifically says to Arjuna, you act on your universal assignment. Fight Without Enmity. If you can fight this war and perform your prescribed duty of universal assignment then you will understand what I am saying. To maintain our body we need to work, if we stop working then our body will not be able to function.
God not only to Arjuna but to everyone of us has given opportunity to act and simultaneously become self-aware. Overnight we will not realize what assignment we have got from God. Like when we enter the school they don’t say that you will become an economist, engineer, doctor, architech, etc. They just start with alphabets with everyone. Once you start studying you will know what further study you want to do. But that need certain time.
Our Karma Yoga, means from our routine work starts. When we are walking are we self-alert, when we are taking a bath are we self-alert? Most of the time we are thinking either for the future or the past but never the time we are self-alert, self-alert means we are not aware of the sensations happening during that act in our body. As if some kind of current is passing through the space inside of our body. This is the alphabet of self-alert. As this practice will increase suddenly you will find that you are become aware of your third dimension, witnessing consciousness of yours.
Once you become familiar with your witnessing consciousness, slowly you will get the direction exactly like what you want to study more from alphabat, you will know direction and will be able to follow the universal wisdom for your action. From this you will know what is your universal assignment.
Why it is said that we need to pass through so many birth, because as we start becoming familiar and act through that universal wisdom it takes so much time. Like you cannot become graduate overnight. Same way you will not realize your universal self, emptiness, witnessing consciousness overnight, it will take its own time.
Meditation starts by being separate from the mind, by being a witness. That is the only way of separating yourself from anything. If you are looking at the light, naturally one thing is certain: you are not the light, you are the one who is looking at it. If you are watching the flowers, one thing is certain: you are not the flower, you are the watcher.
Watching is the key of meditation:
Watch your mind.
Don't do anything – no repetition of mantra, no repetition of the name of god – just watch whatever the mind is doing. Don't disturb it, don't prevent it, don't repress it; don't do anything at all on your part. You just be a watcher, and the miracle of watching is meditation. As you watch, slowly mind becomes empty of thoughts; but you are not falling asleep, you are becoming more alert, more aware.
As the mind becomes completely empty, your whole energy becomes aflame of awakening. This flame is the result of meditation. So you can say meditation is another name of watching, witnessing, observing – without any judgment, without any evaluation. Just by watching, you immediately get out of the mind.
Whatever Maharishi Mahesh Yogi and other people like him are doing is good, but they are calling something meditation which is not. That's where they are leading people astray. If they had remained sincere and authentic and told people that this will give you mental health, physical health, a more relaxed life, a more peaceful existence, it would have been right. But once they started calling it 'transcendental meditation' they have raised a very trivial thing to an ultimate significance which it cannot fulfill. People have been in transcendental meditation for years, and in the East, for thousands of years. But that has not become their self-knowing, and that has not made them Gautam Buddhas.
If you want to understand exactly what meditation is, Gautam Buddha is the first man to come to its right, exact definition – that is witnessing.
Krishna tells Arjuna perform your prescribed duty - Universal Assignment - instead of running away. Even your body also will survive only when it is in action. Become Witness to whole war and perform your duty by Fighting Without Enmity.
