Sure you can, as long as they’re done properly, divided up properly and not completely mixed, and fields like five elements balanced, or essence of mantras and things like that doesn’t “feel” to me like they hinder the progress anything, rather the opposite. It’s fields like MBL, Plasma flaunt, face structure, various brain reparations/BDNF and things that physically repairs and enhances you over time that are the heaviest in my opinion, then comes the energy repairing and expanding ones that are also something you buil over time with various advanced fields (and the reward from that is more physical energy, mental energy, as well as “field”-energy, i.e you can play more fields and get results)
That is my experience at least.
The problem is when people begin listening to a ton of stacks of different categories without having the capacity for it, pretty much what I did - so stick to what you’re doing, it’s what I would have told my beginner self.
