I am sure all recognize your illustration and we all are here to learn a lesson.I feel like at a spiritual level I am quite immature; like I have had spiritual experience from many lifetimes, and lifetimes with spiritual experience, but it didn't translate into a lot of spiritual maturity; I feel like I've walked the egoic path many times.
It depends how you see the egoic path.
Of course trust-faith in the guided teachings of Buddha is not the same as trust in our habitual (compounded) self.
Discernment can be very helpful for us, or looking inside. I remember a saying that to do so, is a much bigger adventure then to do a travel around the world. But mostly we are not interested in that, or better said the mental activity we are so used to identify with, we just trust. Because that we know and we are. ( ?)
If we grasp to-or identify with the changing mind, I copy something;" it includes sense perception, verbal and abstract thought, emotions, feelings of happiness and unhappiness, attention, concentration, intelligence..." that is then what you mean with ego or independent self? Because that is what we know and accept we are. I feel that importance of " we know" is trusting in these perceptions, feelings and so on.

Inquiry, discernment, rushan by guidance, oh well I lack more names, (however it is called is not the importance) to see how there is grasping in own mind and how there is no grasping, this is a way then to allow clarity to arise on our path. Or to allow suffering to decrease what we can only wish for all and all to be so. There are many different ways, there are little extra helps.
We can mature to recognize what is grasping or clinging.
Other ways from mistaken basis comes even grasping to Buddhism, to my practice, mine, I am such or such Buddhist…, all this can turn in grasping while the meaning is to be freed from this clinging habit, and so not to grasp to what should liberate from such.
Faith however is so important, at least for me.
Grace as you said as a support. I agree, the four boundless ones can shine through it. Best wishes.
