No. The sheer fact of learning CHANGES your mind. It adds new knowledge. Therefore it is changed.
If you cannot change your mind then you cannot learn.
Though I think you may agree just that first sentence is false as far as I can tell logically. Learning is change.
To learn entails a change. I cannot dispute that. I just don't think it is Mind which changes. The ideas one knows or accepts as valid change with learning. But the mind, that is perspective, attitude, isn't it? which can stay the same longer than the thoughts one thinks.
