Answer: In principle, “the neighbor” is every person in the world. But for us that is too much. For now we do not yet know how to treat our enemies and opponents correctly. This has to be learned separately.
Therefore, for me the “neighbor” is my friend in the group, a person who wants to unite with me to attain the spiritual goal. This is the condition we have to carry out in the group. We might think badly of our friends and look at them critically, but if we nevertheless try to create the right network of interconnection among us in our spiritual work, if we don’t want to hold grudges against others in any of our thoughts, desires, aspirations, or intentions, by that we already extend threads toward each other.
Until then, this network will only bring us troubles and bad sensations. But as soon as we breathe life into it with our attitude, devoid of criticism and mutual blame, we will immediately feel the electricity flowing between us, will feel how the air in the group grows thicker and turns into “jelly,” connecting us all into one whole.
That is exactly the feeling one gets: The air gets denser around us, turning into a liquid and then into a viscous substance, becoming a gradually solidifying “dough” until we see that we are like raisins embedded into our common “pie.”
