Whenever there is a decline of righteousness, O Arjuna, and the rise of unrighteousness, then I manifest myself.
We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we wish to be in future can be produced by our present actions; so we have to know how to act.
Can the world exist without one to cognise it? Which comes first the being-consciousness or the rising-consciousness? The former is always there and eternal; the latter rises and disappears. It is transient.
When there is harmony in the home, there will be order in the nation. When there is order in the nation, there will be peace in the world.
