First is the certainty by intellectual conviction called "Illmul-Yakeen,” Second is the certainty of “Anicol- Yakeen" through actual “Seeing”; and the third, the certainty of certainties, is by "Becoming" or "Hukkal-Yakeen."
What the Vedantists say about our being one with God,—even that is not the intellectual conviction of ''Illmul-Yakeen,” because when we hear that we are one with God, we imagine only what the intellect grasps temporarily. The temporary understanding can check the conviction, and nothing can upset the holder of that conviction, and when one actually begins to see that one has grasped permanently, then the "Yakeen" or certainty of conviction can be said to be spiritually firm for all time. It is only after one becomes united with what one IS that the certainty of conviction is Dnyan or "Hakul-Yake en."
Now, you all are ordinary men. This knowledge of manhood on your part does not depend upon intellect or reasoning whatsoever. You just know that you are men. None of you ever thinks, "I am a man, I am stone," etc. That is because your knowledge that you are men is self-knowledge of your manhood, and is not the outcome of a mere belief based on what you hear about the feelings and experience of others. Similarly, when you actually feel and find that you have become God, you are then really God; and this "becoming " is the knowledge which the Master can and does impart at the right moment in literally no time at all.
True Mahatmas and Walis can and may give the shadow of knowledge to anyone by influencing through a touch, sound or sight, the centers and seats of knowledge; but even that shadow may be enough to make one lose one's physical body.
We all are, in a way, hypocrites, inasmuch as we always try to justify ourselves, right or wrong. According to the Vedantists and the Sufis, God does everything; everything is done according to His Will and in accordance with His laws. In a way, that is all right; but being short of one truth, the whole of it is not right. And the lack of truth is the lack of experience behind the assertions. Without having gained the actual experience, to act according to facts of experience is not only silly like a tutored parrot expressing love to a girl, but such assertions based on mere reasoning and logic lead to lust and dust. The reactions of the actions based on such "ignorance of knowledge" are too terrible to contemplate, apart from other consequences like lunacy or nervous breakdown.
