The same Holy Spirit and prayers that led all of Christianity up to and including Martin Luther to accept what Jesus Christ Himself said at face value or that other post Luther "holy spirit" hanging from a tree and whispering to the individual that they can rely on their Self and Self Alone?
Please, people who rely on their Self are free to do so but when such folks claim those who disagree with them are not relying on the Holy Spirit and prayer they just prove beyond all doubt they're exactly like the Jews who walked away from Christ when Christ said something that fell outside their comfort zone.
Those Jews rejected Christ based on putting their own limits on what was acceptable for Jesus Christ, the Messiah, God Incarnate, to do. People who are drowning in the heresy of Self and Self Alone do exactly the same thing.
They reject Christ saying "This is my body" because they know for sure God Incarnate would never mean exactly what He said and couldn't possibly perform the miracle of making His real flesh and real blood present for us every time the Eucharist is properly presented because such folks know the power of God Almighty is limited to what they can accept.
Are personal Self and Self Alone comfort zones the same as invincible ignorance?
Allegory. Learn it.
