Advanced meditators are not even desirous of liberation anymore - that is just another attachment. There is no liberation. There is no bondage. These are just ideas of the mind.
We don’t sit in meditation to become good meditators. We sit in meditation so that we’ll be more awake in our lives.
People who are advanced meditators don't worry about liberation and self-realization; they instead are interested in the welfare of others and aiding others in their liberation.
Long-term meditators can have a biological age 5 to 12 years younger than their chronological age.
