If you believe you exist because of what you do, then every moment you are unrealized.
What is meaning and why is it important? To a degree the consensus is love. The common ground we can all stand on. It can be diversified and thus enriched, but still there is the connection.
The spectrum of meaning is synonymous with the range of beliefs and these do vary. But one of the most important aspects of bonding is being able to believe in the person you have a relationship with, thus some need for a common context. Agreed upon interpretations of at least some experience.
When you engage a person, you are engaging your experience of the person. They have their own experience of themselves. Hopefully these have some shade of agreement, thus you believe in “them”. You can stand on some of their grounding. People often welcome that, and sometimes need that very badly.
I‘ve heard it said the only thing another person is to you is the experience they give you. Perhaps this is true, and that can be enough to permit connection. It also can foster disconnection, and not much thought goes into it.
Even the context by which one assigns meaning can differ. If the filters share a commonality then no striving need be made. The shared meaning is automatic. But on a world wide level cultural filters differ enough to create real barriers between nations, and it can happen between individual people also. As long as there is a commonality, communication can occur on a similar playing field. But there can be little commonality, and people don’t desire to broaden their sense of meaning in general.
Your thoughts are welcome. Be well friends.
