Undertake any work and perform it such that there is no untruth, unfairness or evil motive in the way you execute it. See to it that the work you do, not only enables you to earn a living, but also benefits the nation and the community you live in. Everyone must observe this purity in their lives. If you thus engage yourselves in right action, you will not be bound by the consequences of action (Karma). You are who you are, based on the past Karmas. Through your present actions you can ensure freedom from birth. Through love, develop faith and earnestness. Through faith and earnestness, you acquire knowledge, and from knowledge you develop Sadhana (spiritual practices) through which you achieve your goal. Hence to strengthen your Sadhana, all these - wisdom, earnestness, faith and love - are quintessential. Love is the most powerful means to acquire control over your senses.
