Actually, it's completely the opposite as anyone who has done it knows. 

Having a coach who uses neurofeedback makes it a lot simpler and more efficient.   I've met a number of people who THOUGHT they were meditating (in a couple of cases they were doing it for years), couldn't see any benefit, and then discovered neurofeedback by accident and learned what they were doing was the opposite of meditation.   The neuro machine showed they were wholly in a beta/conscious state -- if anything, more stressed than usual.   The machine lets you know when you are off-track through a really simple feedback process.

Neurofeedback clarifies how the process feels and once you get the hang of it you don't need neurofeedback anymore because you have experienced the difference between states and know how to relax into a meditative state while also keeping a level of focus over the "monkey mind".   Achieving focus and yet "letting go" is very tough for a lot of people without biofeedback.
