Many are philosophical speculations on the real nature of living beings and of the Supreme and Absolute Truth. But Krishna teaches us that whoever knows him to be God, the Supreme Person, he truly knows everything. With an imperfect knowledge, one can only elucubate on the Absolute Truth; but one who possesses perfect knowledge, without wasting a second of his precious time, engages directly in Krishna consciousness, in the devotional service offered to the Supreme Lord.

The Lord explains here most clearly that this knowledge constitutes the essence of all the revealed scriptures. It must therefore be understood as the Supreme Lord gives it. Thus, the being will develop his intelligence and will establish himself perfectly in absolute knowledge. In other words, by understanding this philosophy which deals with God, the Supreme Person, and by engaging in his spiritual and absolute service, anyone can be cleansed from all the defilements marked by the three gunas.; virtue, passion and ignorance. The path of devotional service is intimately linked with spiritual understanding, and no material defilement can remain where it is practiced. The devotional service offered to the Lord, and the Person of the Lord, because both spiritual, are one and the same. Devotional service, in fact, is part of the internal energy of the Lord. It is said of the Lord that he is the sun, and of ignorance the darkness. And where devotional service is present, appropriately led by a genuine spiritual master, there can be no question of ignorance.

In the course of devotional service performed in the company of pure beings, fully absorbed in Krishna consciousness, certain elements need to be quite dominated, especially our weaknesses of heart. The first, which brings about the first fall, is the desire to dominate material nature. It has the effect of leading the holy being to abandon the service of love and devotion offered to the Supreme Lord. And when this tendency to dominate material nature increases, then the second weakness manifests itself: attachment to matter and to the possession of matter. The problems of material existence come from these weaknesses of heart.

All beings should embrace Krishna consciousness, engage in devotional service; thus, they will acquire intelligence and become pure. Unless we come to that level where we know and understand Krishna and where we engage in the service of love and devotion to our Divine Self, we have not attained perfect intelligence, even though it would appear to be it to ordinary people. The Lord indicates that it is very difficult to know Krishna until one is free from all the consequences of his sins. To understand, we must first wash away all filth, all sinful acts. But the power and the purity of the service of love and devotion are such that once you engage in it, you naturally reach the level where you are freed from sin.
