In the ephemeral journey of life, where connections can be short lived, the "proper salutation" could signify the value of significant, sincere, and thoughtful interactions. It recommends a recommendation of shared struggles and a recognition of our common humankind.

It beckons individuals to foster connections and interactions rooted in empathy and understanding, reminding us that while we might each be browsing our own currents, we are all part of the very same large and interconnected ocean of presence.
