Why does the mind find new techniques difficult?

Q. Why when I'm shown a technique for healing in meditation does the first mind find it difficult to replicate and use it for healing?

A. Established grooves and patterns. Just as water flows within the grooves it has formed over years, the mind flows within the grooves it has created over time. It helps to do a practice with someone who does it well or with some kind of support, until one's own mind creates new flows and can sustain itself independently.
