What a tragedy if that moment finds them unprepared or unqualified for that which could have been their finest hour.
For a warrior, nothing is higher than a war against evil. The warrior confronted with such a war should be pleased, Arjuna, for it comes as an open gate to heaven. But if you do not participate in this battle against evil, you will incur sin, violating your dharma and your honor.
Don't waste life in doubts and fears; spend yourself on the work before you, well assured that the right performance of this hour's duties will be the best preparation for the hours and ages that will follow it.
Go on bravely. Do not expect success in a day or a year. Always hold on to the highest. Be steady. Avoid jealousy and selfishness. Be obedient and eternally faithful to the cause of truth, humanity, and your country, and you will move the world.
