Society can be improved only by self-sacrifice.
Heaven and earth are eternal. They are eternal because they do not exist for themselves. In the same way, a truly holy person does not live for himself, and therefore he can become eternal, and can achieve anything.
There is only one law, both in your personal and social life: you want to improve your soul, you should be ready to sacrifice it.
The improvement of man can be measured by the level of his inner freedom. The more a person becomes free from his personality, the more freedom he has.
