This book has helped me tremendously: "Heal Thyself" by Queen Afua.
I now know that longevity is a way of life...a tried and tested method used by our ancestors.
"...Fast 24 hours every week on your 'Holy Day' or 'Accra Day,' which is the day of the week on which you were born..." -- page 37, Heal Thyself by Queen Afua.
When I read that meat was nothing more than dead animal flesh my stomach turned. As a result of reading this I have been a vegan since February 2005.
The reason that our ancestors lived so long is due to the fact that they ate no meat, just grains, lentil, nuts, seeds, sprouts, and spirulina.
They ate live foods to oxygenate and revitalize the body rather than dead animal flesh which causes dis/ease:
high blood pressure
premature aging....to name a few.
Praying, fasting and meditating work well in combination with one another.
