When you perceive that something is 'wrong' with someone else, and that this wrongness does not apply to you, you are SEVERELY MENTALLY ILL.
When you perceive that what applies to another person, due to their apparent separate free will and the idea that they are supposed to be responsible for what they do, in isolation, you are SEVERELY MENTALLY ILL.
When you think that its possible for you to do something to someone else, or to have an attitude or judgement toward them, which does not apply to you in any way, you are SEVERELY MENTALLY ILL.
When you believe that someone else clearly is the guilty party and that you did not do anything whatsoever to ask for mistreatment, and that you have been victimized, and that you are completely innocent and they are completely guilty, you are SEVERELY MENTALLY ILL.
When you hate someone or judge them or are disgusted by them or offended by them or they seem to be totally crazy or they are your worst enemy, in which you are none of these things, you are SEVERELY MENTALLY ILL.
In all the ways of perceiving reality, when you perceive that there is a SEPARATION between what applies to you, and what applies to another, that is MENTAL ILLNESS. And this is the foundation of ALL mental illness. A belief in separation, in all its forms and flavors, is mental illness.
When you perceive that something is happening to you which you did not ask for, when you are receiving something you did not choose, or that you are not receiving you what you did attempt to ask for, that is also mental illness.
When you believe that death is inevitable and that it is going to happen to you against your will and that you will be a passive victim of it, that is also mental illness.
You will notice that the above describes THE MAJORITY OF HUMAN KIND. That is because the majority of human kind IS MENTALLY ILL.
To understand WHY this is mental illness, you need to understand how the mind is supposed to function and what is NATURAL for the mind, as opposed to unnatural. All of the attitudes listed above are unnatural and are NOT normal. They are very commonplace, but they are not normal.
The mind, in every person, is not ever in any way supposed to operate in the realm of separation. Your mind is meant to be whole, which means not only that it is whole within itself, but also that it is part of a greater whole in which all minds are joined as ONE MIND.
This means that everyone shares the same mind. This One Mind is the mind of God. When your mind is One with the Mind of God, you are SANE. God is permanently whole and permanently sane and there is no separation of fragmentation in God's mind. You can share God's mind, and that is your NATURAL CONDITION. And it is in sharing God's mind fully that you MUST experience PERFECT HEALTH - perfect divine immortal health.
When your mind is separated off from the whole, and therefore sees itself as separate and limited, it will also see itself as containing limitations and separations. This is what gives birth to EGO. The ego is INSANITY. When there is ego in your mind, i.e. a lack of wholeness, a lack of oneness, a lack of unity with God, you WILL experience insanity - mental illness.
So then as you go around the world perceiving that a given person is "not you", and another person is also "not you", and that there is not something IN them that is exactly the same as what is in YOU, you are in mental illness. You have entered into a private hallucinatory world of separation and division and SELF ATTACK. As soon as you believe in separation in any way, your whole mind must attack itself in an attempt to set one part of itself against the other part. This self attack produces ALL SICKNESS, and all sickness is a form of MENTAL ILLNESS.
Once you are in mental illness, you will perceive that other people are separate from you, that there are separate rules that apply to them which don't apply to you, that what they will is different from what you will, that something can apply to them that does not apply to you, you are in mental illness. Once you start to treat them in a different way than you treat other people, or react to them differently based on their behavior, or have a different attitude of specialness based on who they are or what they exclusively do for you, you've moved away from the UNCONDITIONAL LOVE which is the condition of the WHOLE mind, and have entered into conditionality. Conditionality is insanity.
So then when you are hating the political candidate for the opposition, or when you are against that other sports team, or when you hate that person who seemed to do something to someone against their will, or when you judge someone for the form that they appear to take, or when you can only love a special person and nobody else, or when you believe that you are right and someone is wrong, or that you are good and someone else is bad, THAT IS MENTAL ILLNESS.
It is not natural. It is not normal. It is extremely common and almost everyone on this planet IS mentally ill. This IS a crazy world, but it doesn't have to be.
So when we talk about mental illness, let's be clear about what sanity really means (One shared mind of wholeness and peace and unconditional love), and that anything other than this is mental illness in one form or another. Everyday people rising up 'against' some other group of people, is mental illness. Everyday people attacking some other group righteously because of how that other group is 'less spiritual' or 'less honest' or 'less good' or whatever, that is mental illness. And its YOUR mental illness, not theirs.
All forms of separation are mental illness. All perceptions of separation are mental illness. And all other commonly recognized types of "mental illness", which people would normally call mental illness, such as paranoia or schizophrenia or psychosis or whatever, those are just the more noticeable EXTREMES of mental illness. That doesn't mean that all the other people are SANE. Almost every psychiatrist on the planet is insane. Almost every doctor or nurse on the planet is insane. Almost every pastor of churches or preacher in religions is insane.
The only sanity is in God, with God, joined with God, one with God, as God's Holy Son who is permanently sane and whole and complete, devoid of separation and lies. Only in TRUTH is there sanity. So before we judge other people for being insane or 'not right', let's remember that WE are just as insane and we need to work on our own mental health instead.
