Anyone (!) alive
of all sentient beings,
any living person could have been
our mother, once upon a time !
Taking into consideration,
the laws of karma, cause & effect & reincarnation,
any newborn, somewhere on the world, could be someone
we knew who died or could be someone from our family
or a close friend, who died in the past.
could as such be a Soul
or consciousness that was
once our mother !
