There is no peace or happiness in our worldy life. Circumstances create turmoil and annoyance.
Everyone is hankering for happiness because by nature we are happy : anandamayo ‘bhyasat (Vedanta-sutra 1.1.12). As spirit souls we are naturally happy, blissful.
Joy can only be experienced when we offer our love to Krishna.
We are like fish out of water. Just as a fish cannot be happy unless he is in the water, we cannot be happy apart from the spiritual world.
