In order to know a subject or science, practical is as important as the theory. The same is true of God-Knowledge. Saints do not teach others by word of mouth, but through their practical life. Action is found to be more effective than the word. The spiritually enlightened devotees always speak through their actions. They practise what they say and inspire others to do the same.

When we go to the school, we are taught a particular subject by a teacher who is thoroughly familiar with the same and knows how to teach it. Similarly, God knowledge can be revealed to us only by a person who is fully familiar with it. Only such a person can establish our relation with God. The only condition is that we must possess the requisite desire, the requisite will to receive the divine knowledge. Without a strong desire for self realization, man may suffer from hesitation and miss the valuable treasure. This quest is rather very essential.
