From what I read, it seems that spiritual emergencies often lead to diet changes, and these are quite individual and may also change over time.
For me, I went from vegetarian to eating heavier food including red meat, dairy and heavier grains such as oatmeal. It has felt necessary, and nurturing and grounding. Especially slow cooked (crock pot) meat stews have been good, and also brown miso and beef broth. I have also found myself eating more chocolate and sugary foods at times, where I before almost didn’t at all.
In The Stormy Search for Self, the Grofs talk about these types of diet changes as quite common. The body needs more nurturing and grounding, so seeks heavier foods, and it also sometimes needs quick energy and seeks our sugary foods.
That said, I still find fruits and vegetables to be essential in my diet. I also make sure to drink plenty of water, usually in the form of spice and herbal teas. And my diet changes with the seasons and the day, depending on what feels right and nurturing, as it has for a long time now.
It is a little odd to find myself eating the type of foods I earlier judged others for eating. And yet, that too is part of the humbling process. I find myself eating as anyone else, I find myself judging as anyone else, and I find myself humbled as anyone else. It’s part of the human experience.
I still see eating lower on the food chain as essential for our individual health and well being, and also for the health and well being of society, ecosystems, the earth, and future generations. I don’t justify or champion meat eating just because I find myself doing that now. And I still probably eat a lot less meat than what’s typical in western countries.
