I think the conversation needs a fresh start. I have not achieved mukhti and perhaps my haumei may be forgiven by forum members.
The questions, what is jeevan mukhti, how does one get it, who has it, and how do we know for sure that so and so achieved it, are common to the point of being mind-numbing. They may even be fruitless because the answers depend on tangible proofs of intangible qualities. It is very likely that someone who achieved jeevan mukhti in this lifetime cannot explain the mechanics of it but might try just to be helpful. It is not a matter of techniques that can be demonstrated and tested like taking a rifle apart and putting it back together again. In Sikhism Shabad Guru gives us a different approach so that we do not become frustrated. The answer is in Sri Guru Granth Sahib ji -- and in fact each and every shabad is a key. Here is an example. It is not the only example.
The shabad is by Guru Ram Das, in raag Aasaa, on Ang 11.
ਤੂੰ ਘਟ ਘਟ ਅੰਤਰਿ ਸਰਬ ਨਿਰੰਤਰਿ ਜੀ ਹਰਿ ਏਕੋ ਪੁਰਖੁ ਸਮਾਣਾ ॥

This is not a difficult idea: The "noose of death is cut away" through seva to the Guru. How does one proceed?

It is less taxing if one starts with a shabad and then proceeds. A serious vichaar of this Shabad will answer your questions Roger ji.
