Well, that's all well and good. And you can pursue a perfect diet and get to the point where you are only eating lettuce. And you better make sure it's the right kind of lettuce, grown in exactly the right soil in the right conditions and harvested with its roots on and it better have been exposed to real sunlight, or else.
Although this can seem completely sane, and rational, and sensible, at some point you have to realize, this is absolutely nuts.
The more you try to feed yourself only the most perfect, "harmless", "supportive" foods, and the more you focus on this perfection of picking only what the ego says will not hurt you, the weaker you become, the more vulnerable you become, the more you become sensitive to everything, the more you become affected by everything.
If you keep focusing on trying to be "positively affected" by the world, as some kind of idolized goal, where you only allow into yourself the very best the world has to offer, that's persona bullshit. That's the ego pretending that doing so will make you strong or healthy or protect you. It does the exact opposite. It undermines you inner power. It disempowers you and portrays you as so completely fragile and weak and powerless that you NEED the very very more purest foods as input, otherwise you're going to keel over and die.
You don't want this.
What you want is to get your power back so that you are invulnerable, so that you do not have to care about what you eat, so that you do not have to constantly obsess over trying to find this MYTH of a "perfect diet". All foods are deadly. All foods are toxic. And all foods kill, just so you know. All foods, external foods, supply from outside of yourself, WILL create sickness, if you believe in their power to affect you positively or negatively. It doesn't make any difference that you regard certain foods as profoundly positive versus others there are allegedly negative, both perceptions are ego perceptions that weaken and attack your invulnerability.
As an invulnerable, immortal creator, you do not need food at all. You are sustained by the love of God! You should have no regard for the MYTH that certain foods are better than others, which is a completely unmiraculous state of mind. You should pay no attention to the bullshit stories that make certain things out to be better for you than other things. That's ego bullshit. You should be focusing on how you are absolutely invulnerable, how you do not depend on anything outside of you, how you are not negatively affected by food and how food does not have power over you, positive or negative. You should be focusing on undoing this dependency on it and this belief that different hierarchies of the illusion of food do different things to you. Food does not do anything to you! Stop being a victim.
God is the one source of Life, and food is not life-giving. Food will eventually kill you. And just so you know, people who fast and avoid eating as much food live longer. Do you know why? Because all foods are forms of the illusion of separation and have some aspect of attack in them. They are all special, all of them are limited, all of them have side effects, and none of them can make you holy. Even the most 'pure' of foods which other claim are the 'best' for you, will destroy and attack your body eventually. There is no perfection out there. You even have to go to the lengths of becoming a breatharian, feeding off of environmental chi or whatever, in order to try to avoid the toxic effects of this world. And even then you will die.
It's just stuff. It's just materials. It's just external illusions designed to make you dependent on what is separate from you, so that you will stop looking for the source of Life inside yourself. God it your supply, not the world.
