Hi Ezekiel,
Of course that is what Buddhism is supposed to be about, and of course Christianity is supposed to be about love of neighbor - but it is like the ego co-opts these ideas rather than sincerely practicing or 'applying' it in life. In the case of Buddhism, naturally it threatens the ego. It is of course self deception, and the person doesn't see what they are doing. But in context of what I was discussing, it isn't even so much about someone being full of himself, but I am speaking of ego from a functional perspective. Sometimes the opposite is the case, and when someone is downtrodden like that it is certainly not the time to try to bring about 'ego death' - that would just compound the existing effect of abuse.
Now as far as meditation is concerned, and the relationship between it and mental health and the egoic state of consciousness, it just depends on where someone is at. The rule of thumb seems to be someone who has relatively good mental health would do okay with it, but if someone has lots of issues or essentially an unstable ego structure, then it is best if they practice with some guidance and sometimes not at all. When I was doing meditation retreats there would sometimes be people who have stuff come up and the teacher will recommend they stop meditating and go home.
See basically the point I am making, which is by no means original is that meditation ultimately points to a deeper aspect of the mind - and not so much a technique which brings temporary relief of mental suffering, even if one practices regularly as a kind of maintenance care. When that is seen clearly, which implies seeing through the ego as a relatively superficial aspect of yourself, there is more of a permanent shift in consciousness. In other words it is about a kind of discovery, and not a form of conditioning. Another view would frame it as a developmental process, which strictly speaking you cannot force by using a technique anymore than you can make someone mature physically. This is where the inquisitive aspect comes in, such as koans in the zen tradition and inquiry with Advaita Vedanta.
Now having said that, I would have to add you wouldn't go into this judgement like how you're too much of a mess to do this. In that spirit of discovery, you can certainly try it if you are drawn to meditation. The whole thing is really a very natural process, there's no need to force yourself into a certain type of meditation practice or sit a particular way. If you feel you need guidance and there is no guidance available where you're at, look up the info online and try it out for yourself, and talk with people - just take care to see how you're doing and don't try to force anything. After all the whole thing is about understanding yourself deeply, not trying to fit into someone else's mould of how you should be.
