The conjunction of the seer with the seen is for the seer to discover his own nature.
The powers of purusa and prakrti are designated for Self-Realisation. The purpose of their contact is the blossoming of their innate powers, and the seer's discovery of his own essential nature.
This sutra makes clear that a desire for synthesis or a close association or assimilation between the owner, the 'owning' and the owned has existed since the beginning of civilization.
By the light of pure knowledge, the owner, the seer, perceives and cognises whatever is to be perceived or cognised through his association with nature. If this association is fed by ignorance, it leads the master towards enjoyment, desire, and complaints, and ties him down. But if non-attachment is garnered, it leads to detachment or renunciation - vairdgya.
If the master maintains constant vigilant awareness of his consciousness, associates with nature without attachment and stays a witness, nature (prakrti) leads its owner, the soul, to freedom - moksa.
