I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.

We have to create more and more vegetarians, and help people to understand that it is not only the suffering of the animals (which is what made me vegetarian) but also the incredible harm to the environment, the tremendous amount of greenhouse gas created by the whole vast machinery of intensive animal farming.

Realize that change - whilst we want it to happen fast - is usually the result of a great deal of work, and often comes as a result of a series of compromises (so long as we do not compromise our values).

We can't leave people in abject poverty, so we need to raise the standard of living for 80% of the world's people, while bringing it down considerably for the 20% who are destroying our natural resources.

Cultural speciation had been crippling to human moral and spiritual growth. It had hindered freedom of thought, limited our thinking, imprisoned us in the cultures into which we had been born. . . . These cultural mind prisons. . . . Cultural speciation was clearly a barrier to world peace. So long as we continued to attach more importance to our own narrow group membership than to the ‘global village’ we would propagate prejudice and ignorance.

I urge you to read Eternal Treblinka and think deeply about its important message.

At some point, my body will collapse. But I hope that my brain will still be working so that I can carry on with writing.
