The teaching of the Buddha is
It is well communicated, Immediately apparent, always applicable, of the nature of a personal invitation, progressive, and to be understood individually by the wise.
This is from the Ti Ratna Vandana which I regularly recite.
Part of what the Buddha taught is that total relinquishment is possible. I have confidence that this part of his teaching like all the rest is immediately apparent and always applicable. Even if I fall short of of what I am taught and do not see what is immediately apparent.
"Beautifully taught is the Lord's Dhamma, immediately apparent, timeless, of the nature of a personal invitation, progressive, to be attained by the wise, each for himself." Anguttara Nikaya V.332
