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.
We are shaped by our thoughts; we become what we think. When the mind is pure, joy follows like a shadow that never leaves.
Do not dwell in the past; do not dream of the future, concentrate the mind on the present moment.
