I used to do visualizations, they can help, though to be honest, the AYP method, if you're into moving energy around and stuff, it's been the best method for me, especially because everything is under the hood. Visualisations help you get in touch with "what doesn't seem to be there...yet", but by just keeping at it, it won't really make a difference in the end. Thing with visualisations too... if you feel you're mind is distracted while meditating, they can help ease you into the practice too, which is cool.
One thing though, trust me, I know it seems like "there's this, this and this that I need to fix by moving energy around"... and for sure, meditation can cure certain imbalances, much of it has to do with everyday life though... for that, it all comes down to a little introspection and self honesty here and there. I'd also resist relating everything to particular chakras\\energy and what you've been told they mean... working on those to "fix" that problem. Again... I really admire AYP's "under the hood" approach, I wish I knew about it earlier haha. It's just better to keep the inner working "under the hood", and to grow with what you learn while going inside, rather than filling your head with a whole lotta ideas on chakras and energy movement and "what it means" or "how to fix em" (like "negative energy"... means nothing to me
haha
... it's just more energy to look at. Good or bad, truth is there (on varying degrees... but it's there), awareness is there, that's all you need to grow. You'll always find what you're looking for).
I don't mean to just blab this all out haha, these were just some of my "sticking points", I thought some might help
