The idea of a vital force is described as prana in India and Tibet, qi (chi) in China, baraka by the Sufis, yesod in the Jewish cabalistic tradition, orenda by the Iroquois, megbe by the Ituri pygmies, and the Holy Spirit in Christianity. . . . The vital exhaustion of toxic success results from an uncontrolled leakage of our vital energy. It leads to an exhausted mind, tired spirit, and vulnerable body. . . . We can become what my 'ohana calls "mana suckers", people whose own loss of vitality leads them, often unintentionally, to leech the vital energy from those around them.
