Ants have lots of strength. They can lift many times their weight
Ants have speed. They are always running.
Ants work well together
Ants are not lazy, they are hardworking.
Such traits are valued from our perspective.
However, their effort in their lifetime will go to nought if they do not have the chance to encounter the Teachers and their Teachings.
Are we like ants now busying ourselves with things that will not help us in our Infinite Lives?
Something to ponder.
