While your ego also can put you down, it's not quite as singularly-focused as the critical parent.
The critical parent voice is always harping on you, always nagging you, always criticizing you.
Here's what I offer:
You get the complete visualization meditation that guides you to meet your inner parent and convince it to STOP criticizing you. You can then turn it into a nurturing parent instead.
You can completely END that awful inner criticism after one or two times of listening to this meditation.
