In working with Higher and Lower mind, the greatest challenge is knowing the difference between the two. Higher mind lands as a flash, "this is the way to go now". Lower is much slower and deliberating - the risk being that it controls the flow, making decisions that don't serve your true self. The key is to keep letting go to the spontaneous knowing. Let higher mind decide what to do; let lower mind decide how to do it - but definitely not what to do!
