Spiritual Snakeoil

 The snakeoil salesmen of spirituality
will sell you on the constancy of self.

It will sound something like,

"Although you have changed over the years, that which perceives has stayed the same. You are not the changes, you are that which stays the same and sees the changes."

They must not have been paying attention for any prolonged period of time. If one invests the proper amount of time, honing the mind back at the mind, subtleties and changes appear with greater and greater refinement.

There are changes in the changeless aspects of ourselves. It adjusts slowly, as do our fates, by means of the patterns of the day to day.

Yes, even that which is the perceiver changes. There are many qualities which can change over short and long periods of time: the "size" of one's awareness. the shape. the duration. the emphasis or ratio mixture of sensory flow.
