It is not that nothing happens when the heart, soul, mind, and body is united in the non-conceptual love of God, it is just that is it nothing that is visible, nothing that is audible and nothing that is conceptual ....1 Corinthians 2:9 "What no eye has seen, what no ear has heard, and what no human mind has conceived" -- the things God has prepared for those who love him-- The pure oil metaphor of scripture represents absolute submission to God....which results in the wedding of the lover and the beloved....the union...non-duality...
I understand what you're saying and I agree.
I also can see many can have a still mind through meditation and not experience what you said above.
There is also literally an oil that the human body secretes within. If the mind and body aren't pure, it will not secrete the pure oil.
I like this from the gospel of Philip:
"The chrism is superior to baptism, for it is from the word "Chrism" that we have been called "Christians," certainly not because of the word "baptism". And it is because of the chrism that "the Christ" has his name."
"The Christ or Chrism" is what is referred to as that organic and pure oil secreted within the human body.
The problem with most sects are that they don't experience that within because they see that oil exoterically and new-agey for outward shows and rituals. They use the church buildings to perform their exoteric shows rather than understand that their human body is the church and that the oil is organic and produced within the human body.
One is external idolatry and one is going within.
