Sri Ramakrishna had a famous disciple called Vivekananda. In an address in 1900 Vivekananda said this:
One of the greatest lessons I have learnt in my life is to pay as much attention to the means of work as to its end. He was a great man from whom I learnt it, and his own life was a practical demonstration of this great principle. I have been always learning great lessons from that one principle, and it appears to me that all the secret of success is there; to pay as much attention to the means as to the end.
Our great defect in life is that we are so much drawn to the ideal, the goal is so much more enchanting, so much more alluring, so much bigger in our mental horizon, that we lose sight of the details altogether.
But whenever failure comes, if we analyse it critically, in ninety-nine percent of cases we shall find that it was because we did not pay attention to the means. Proper attention to the finishing, strengthening, of the means is what we need. With the means all right, the end must come.
