Since you have been a member of my various groups dedicated to supporting contemplatives for decades, then you must be aware of our findings here, which are:
1) No one who teaches meditation anywhere seems to have any understanding of what meditation leads to, but there are lots of assumptions, most of which we have found are erroneous.
2) Most of the people who report depth in meditation consistent with samadhi almost always practice observation of the breath, which is often referred to as "bare attention," meaning the mind is not deeply engaged in observation of the breath, but simply observing it. And, this is what I have been doing for 50 years. So, while I will admit that I may have a special natural ability in meditation that allowed me to get to samadhi within weeks of the beginning of my daily meditation practice 50 years ago; nonetheless, I have been studying meditation and what it leads to, which is called mysticism, the whole time, and at no time did I ever meet a guru who understood our interest here. So, may I suggest that you dump the fantastic belief systems that most meditation teachers shroud their delusional beliefs in and just observe your breath when you meditate and be mindful of any phenomena that arises when you meditate, and when something in the range of our discussions here arises, then use that as your new meditation object, meaning just bring your attention to it until new phenomena arises, then shift your attention to that new phenomena. And, try not to bring any assumptions to that practice.
