From my own experience, I can say that sticking to one path, instead of going down many different ones, has allowed a depth of knowledge and wisdom to emerge. I discovered for myself that a repetitive practice on the spiritual path builds a solid foundation. Whether yoga, meditation, martial arts, journaling, etc., the continuity serves as an anchor and facilitates the discernment because you become rooted in the integrity of the practice. When new paths appear, you have a base to which to return to for contemplation and clarity.
One cultivates discernment through the practice of Reiki. You come to realize in Level 1 that your presence alone is a gift and that you have the ability to channel Universal Energy, regardless of your past experience, background, or belief system. You can travel the world from your armchair by sending Reiki in Level 2. You can begin to see the great light of Reiki in yourself in Level 3 and how it serves as a reflecting mirror for others in your life. You begin walking the master path and realize that there is no ending point to it: you are now more responsible for your words and actions and in training others.
Discernment is an ongoing process, and it is a mechanism that allows us to look at the outside world for guidance while going inward for confirmation. The more we are aware of who we are as human beings and Reiki practitioners, the more successful we are in our practice in reaching out to the world.
