Patanjali is the greatest scientist of the inner. His approach is that of a scientific mind; he is not a poet. And in that way he is very rare, because those who enter into the inner world are almost always poets, those who enter into the outer world are almost always scientists.
Patanjali is a rare flower. He has a scientific mind, but his journey is inner. That’s why he became the first and the last word: he is the alpha and the omega. For five thousand years nobody could improve upon him. It seems he cannot be improved upon. He will remain the last word – because the very combination is impossible. To have a scientific attitude and to enter into the inner is almost impossible. He talks like a mathematician, a logician. He talks like Aristotle, and he is a Heraclitus.
Try to understand his every word. It will be difficult; it will be difficult because his terms will be those of logic, reasoning, but his indication is towards love, towards ecstasy, towards God. His terminology is that of the man who works in a scientific lab, but his lab is of the inner being. So don’t be misguided by his terminology, and retain the feeling that he is a mathematician of the ultimate poetry. He is a paradox, but he never uses paradoxical language – he cannot. He retains a very firm logical background. He analyzes, dissects, but his aim is synthesis. He analyzes only to synthesize.
So always remember the goal – don’t be misguided by the path – reaching to the ultimate through a scientific approach. That’s why Patanjali has impressed the Western mind very much. Patanjali has always been an influence. Wherever his name has reached he has been an influence because you can understand him easily; but to understand him is not enough. To understand him is as easy as to understand an Einstein. He talks to the intellect but his aim, his target, is the heart. This you have to remember.
