And the answer lies in enchantment and disenchantment.
For instance when we fall in love it takes us over and we think it will last forever. But in real life, we fall in love for a time then we fall out of love - first we are enchanted then, after a while, we become disenchanted.
At the point of disenchantment we quite often make the mistake of blaming the other person - we say, they are not what we thought they were - or we can start to see their faults. But in fact the other person hasn't changed - they are still the same whole person. Tne only thing that has changed is that we have changed our minds.
And this is what learning is. It is simply changing our mind.
It is not putting something into our mind, it is becoming familiar and comfortable with the process of changing our mind.
The corollary is that we start to see that we are not our mind - if we can change our mind and the world doesn't end, we see we are separate from our mind and indeed even our personality.
In other words we become delightfully free of our minds.
We are not losing our minds, we are coming into their full possession.
Another way to look at it is in order of learning. So keeping one idea in your mind is the first order. Keeping two ideas in your mind at the same time is the second order and keeping three ideas in your mind at the same time is the third order and so on.
But the big step is from keeping one idea in mind to keeping two ideas in mind, 'cause once you learn two there is no reason not to have three or even four.
However in taking this big step from one to two, we find we are quite naturally disorientated. We don't know what to do - which idea should we folllow?
But after a while we learn that, "not knowing what to do", is as sign learning it taking place.
So first we are enchanted with MBTI then we become disenchanted with MBTI, but this is not the time to reject MBTI. Now is the time to keep the enchantment and the disenchantment in your mind at the same time.
In that way we are learning and indeed we are transcending, but not rejecting, MBTI.
