Learn to be thankful, because appreciation and gratitude are strengths which detoxify the organism, neutralize poisons, renew materials

"Learn to be thankful, because appreciation and gratitude are strengths which detoxify the organism, neutralize poisons, renew materials. So, every day say: ‘Thank you, thank you, thank you, thank you, thank you,' several times a day.
Human beings are ungrateful creatures. They are ungrateful towards the Creator, ungrateful towards the whole of Nature, ungrateful towards each other, and what is worse, they find their attitude completely normal. All they remember about their lives day to day are the bad things, so is there really anything to be thankful for? Well yes, there is, and quite a lot at that. There are lots of reasons to be thankful. And disciples who want to progress along the path of evolution must learn gratitude, because it is gratitude that will one day allow them to find the key to the transformation of matter, their own matter. Try to understand this fully. Of course your efforts may well not change anything about your physical appearance, but the nature of the elements entering the make-up of your matter will be different. It will be more sensitive, more subtle, more resistant, and you will feel all your physical and psychic organs functioning better."
