Our loving propensity expands just as a vibration of light or air expands, but we do not know where it ends. The Nectar of Devotion teaches us the science of loving every one of the living entities perfectly by the easy method of loving Kṛṣṇa. We have failed to create peace and harmony in human society, even by such great attempts as the United Nations, because we do not know the right method. The method is very simple, but one has to understand it with a cool head. The Nectar of Devotion teaches all men how to perform the simple and natural method of loving Kṛṣṇa, the Supreme Personality of Godhead. If we learn how to love Kṛṣṇa, then it is very easy to immediately and simultaneously love every living being. It is like pouring water on the root of a tree or supplying food to one’s stomach. The method of pouring water on the root of a tree or supplying food to the stomach is universally scientific and practical, as every one of us has experienced. Everyone knows well that when we eat something, or in other words, when we put food into the stomach, the energy created by such action is immediately distributed throughout the whole body. Similarly, when we pour water on the root, the energy thus created is immediately distributed throughout the entirety of even the largest tree. It is not possible to water the tree part by part, nor is it possible to feed the different parts of the body separately. The Nectar of Devotion will teach us how to turn the one switch that will immediately brighten everything, everywhere. One who does not know this method is missing the point of life.
As far as material necessities are concerned, the human civilization at the present moment is very much advanced in living comfortably, but still we are not happy, because we are missing the point. The material comforts of life alone are not sufficient to make us happy. The root cause of our dissatisfaction is that our dormant loving propensity has not been fulfilled despite our great advancement in the materialistic way of life. The Nectar of Devotion will give us practical hints how we can live in this material world perfectly engaged in devotional service and thus fulfill all our desires in this life and the next.
The Nectar of Devotion is not presented to condemn any way of materialistic life, but the attempt is to give information to religionists, philosophers, and people in general how to love Kṛṣṇa. One may live without material discomfiture, but at the same time one should learn the art of loving Kṛṣṇa. At the present moment we are inventing so many ways to utilize our propensity to love, but factually we are missing the real point: Kṛṣṇa. We are watering all parts of the tree, but missing the tree’s root. We are trying to keep our body fit by all means, but we are neglecting to supply food to the stomach. Missing Kṛṣṇa means missing one’s self also. Real self-realization and realization of Kṛṣṇa go together simultaneously. For example, seeing oneself in the morning means seeing the sunrise also; without seeing the sunshine no one can see himself. Similarly, unless one has realized Kṛṣṇa there is no question of self-realization.
