There's never harm in reviewing and revising the basics of one's practice.
Sometimes, we have a tendency to think something along the lines of, "Well, I did that so long ago; I learned how to do this or that a long time ago; I don't need to practice that."
Sometimes, that's true, and other times, going back to the basics can allow one to build on and strength those skills.
Of course, at some point, we do have to move on from the basic and take on more robust practices. The point of reviewing the basics is to open us to something more complex. Then the higher levels of complexity can also become their own "basics" that we use.
The other side is that some of us try to jump ahead to more complex practices without mastery of the basics. I'm 100% guilty of doing this. There's a lot that I've missed over the years because of my sheer lack of focusing on what I should be doing and being exposed to way too many meditation methods and energy practices in way too short of a time without having a guide of any sort.
The Aquarian Catholic Spiritual Community is a great remedy for this- we have focused but flexible sort of path, and the liturgical and astrological years allow us to address different energetic concerns at different points.
Have you found yourself taking on too many practices?
