The Sutras have a power and a timelessness about them which demonstrate the accuracy with which they pinpoint the basic truths of human evolution from subservience to personality clamours to the serene freedom of the soul.
Most human problems today originate in selfish desire; the prostitution of the feeling nature to self-centred action. This is also brought out clearly in the teaching of the Lord Buddha, the treading of the Noble Eight-Fold path providing the only way out of the maze: "Right Values; Right Speech; Right Mode of Living; Right Thinking; Right Expression; Right Conduct; Right Effort; Right Rapture or True Happiness". These are attributes of the soul.
Patanjali explores exhaustively the means, the techniques and the mental posture which create the connecting thread between the form-centred personality and these stages towards spiritual achievement and soul fusion.
An extract from the Tibetan teacher, written in 1934 briefly explains the intent of these teachings: “The books that I have written are sent out with no claim for their acceptance. They may, or may not, be correct, true and useful. It is for you to ascertain their truth by right practice and by the exercise of the intuition. Neither I nor A.A.B. is the least interested in having them acclaimed as inspired writing, or in having anyone speak of them (with bated breath) as being the work of one of the masters. If they present truth in such a way that it follows sequentially upon that already offered in the world teachings, if the information given raises the aspiration and the will‑to‑serve from the plane of the emotions to that of the mind (the plane whereon the Masters can be found) then they will have served their purpose. If the teaching conveyed calls forth a response from the illumined mind of the worker in the world, and brings a flashing forth of the intuition, then let that teaching be accepted. But not otherwise. If the statements meet with eventual corroboration, or are deemed true under the test of the Law of Correspondences, then that is well and good. But should this not be so, let not the student accept what is said.”
