The Roman poet Publius Ovidius Naso, known as Ovid says
“Dripping water hollows out stone, not through force but through persistence.”
We can’t force a certain realization or outcome but if we are persistent with our service then that’s when the magic happens.
Nowadays there are so many technological tools to stay connected and to cultivate relationships. Use whatever tools you think practical for your situation in order to stay in touch with your crowd.
If you have the ability to expand your crowd then do so, but that also isn’t necessary. Having a close-knit group can be very powerful in itself.
Maybe one of your guests will become a future host and naturally they will want to invite their circle of friends.
Your small group may organically grow exponentially. You never know.
The key is persistence.
If there is persistence then you will see a natural growth that may expand further than you can imagine.
Just keep at it and Krishna will do the rest.
