Get negative thoughts (away from yourself / out of your mind)

Question

I was wondering as which one of the following structures sounds more natural to be said to Yoga students by their master?

a. Get negative thoughts away from yourself.
b. Get negative thoughts out of your mind.

I was wondering if there is any better (more idiomatic / natural) way to imply the same message if my offers do not make a good sense.

Answer 1

(b) is what people normally say. A fluent speaker would be unlikely to say (a). It's "get negative thoughts out of your mind" or "out of your head".
