Are there videos of people using Qi to build good homes for the homeless? To send lovingkindness out and stop violence in their neiborhoods? to stop famine? to make food gardens grow abundantly? to help families be peaceful and happy, kind to their kids? there is a lot of suffering in the world that could be aided by strong and healthy people who care, and who have the power of their own health and capacity to direct their strength and efforts.
If one has great power of Qi, I would hope they would use it to help in the world where there is great need of help. To reduce the situations and circumstances that cause suffering--they are not all personal causes, many are social, group...just ask the people of Iraq if they asked for war. Or the millions held in slavery today if they are choosing this. It would and will take great love to address the causes of war, slavery, and other forms of suffering in the world. I hope those who aspire to "great Qi" will aspire to make use of it in service of love and harmony in the world.
This is my appeal: if you have a power to do good, do it. Don't waste it your energy on frivolity and show. Let your heart be moved, and make a difference to those waiting for the aid of others, for love, for kindness. As human beings we need to act in the realm of human beings to bring harmony there. If you have a power to spread harmony, to spread peace, to spread love, please, rejoice in that, use that.
