I reached in experience the nirvana which is unborn, unrivalled, secure from attachment, undecaying and unstained. This condition is indeed reached by me - deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realised only by the wise.
A yogi who perceives his real Self as separate from his active senses and their objects never becomes attached to anything. He is aware of the dream nature of the universe and watches it without being entangled in its complex but ephemeral nature.
Attachment is the great fabricator of illusions; reality can be obtained only by someone who is detached.
