The references which follow come from lay thinkers and writers:

  1. Making Do with More…the November 25, 2019 writing from Franciscan priest and author Richard Rohr’s website. The text of this Daily Meditations is from speaker and author Charles Eisenstein who advocates against the blind consumerism which has engulfed our society. In contrast to our over-indulgent consumerism, which is killing the planet, I try to practice an old Yankee saying, “Use it up, wear it out, make it do, or do without.” We have to move away from the fear and ignorance based social practices which Eisenstein describes in this writing. The practice of gratitude can assist our evolution.
  2. Love Without Conditions, Reflections on the Christ Mind…a short text by Paul Ferrini which contains a 3 page chapter on Gratitude, as well as other beautifully and clearly written short chapters on important spiritual concepts. This is a 1994 writing. One of my surgical patients gave me this book back in 1998. I am still contemplating the messages. Here are the opening words from the chapter on Gratitude…You cannot mention abundance without also mentioning gratitude. Gratitude stems from worthiness and supports the experience of abundance. On the other hand, ungratefulness and resentment stem from unworthiness and reinforce the perception of scarcity. Each is a closed circle. To enter the circle of grace, you need to bring love to yourself or another. To enter the circle of fear, you need to withhold love from yourself or another.
  3. Prayer…a writing on this website from August 26, 2018. This writing expresses the prayerful flow of heart based consciousness in our lives. The heart is the conduit of prayer.
  4. The Prayer of Life, Heart Electromagnetics, Part III…this Journal writing from May 1, 2017, is the 3rd of 4 writings where I attempt to enumerate how the heart works and what it is doing besides pumping blood around. The science presented in this writing has important positive social implications.
  5. Hoping for Snow in Dark December: A Balm in Troubled Times…a 76 year old grandfather writes some simple suggestions and wisdom for his 4 year old grandson. It is a writing about appreciation of life’s little daily wonders.
