We have our human characteristics, but our souls are very unconditional and are ready and open when we sing this beautiful line, I love all humanity.  If we just do the practice, practice makes perfect.  Our hearts and minds will become more and more aligned with this line.  We might not be there yet.  Nothing to be embarrassed about, it’s perfectly normal but, at the same time, if we want to become a more loving person, if we want to be a better version of ourselves tomorrow, then chanting this line will help us get there.
