This sutra brings us right back to the great basic duality of manifestation, the union of spirit and matter. It is their interplay which produces all the form-producing modifications or activities on the various planes and which is the cause of the limitations which pure consciousness has imposed upon itself. In a small commentary such as this it is impossible to enter with any fullness into this subject. All that it is possible to do is to touch upon the subject as it affects man himself.

It might be summed up as follows: All pain and [152] sorrow is caused by the spiritual man identifying himself with his objective forms in the three worlds and with the realm of phenomena in which those forms have their activities. When he can detach himself from the kingdom of the senses and know himself as the "one who is not that which is seen and touched and heard" then he can free himself from all form-limitations and stand apart as the divine perceiver and actor. He will use forms as he desires in order to attain certain specific ends but is not deluded into regarding them as himself. Students would do well to learn to hold the consciousness that in the three worlds (which is all that concerns the aspirant at this stage) he is the highest factor in the well-known triplicities:

Through an understanding of the nature and distinctions of matter he will come to a comprehension of the world of form which has held his spirit a prisoner for so long. This Patanjali points out in the next sutra.
