What you are really asking is, “How can I avoid being a grown-up?”
The simple answer is, you can’t.
Evolution is greater than you.
Growing up is a natural part of life.
Expanding beyond our mental limitations is a normal part of our psyche’s development.
The problem is that Western culture has prioritised external progress/advancement to its detriment. Had it paid a little more attention to its spiritual development, more understanding & support would now be available about this extraordinary time in life, as it is in indigenous communities where connection to spirit remains strong.
Spiritual transformation can be likened to a snake shedding its old too-tight limiting skin. If the snake doesn’t moult, growth stalls and the unyielding skin becomes parasitic, eventually turning on itself and causing premature death.
