Why devotees insist
that they are servants of God? Is there joy in service?
The answer is a big yes! It is because all souls
serve happiness. We (souls) do anything and everything to acquire
joy, happiness, thrill, peace...name it anything.
Which makes all souls servants of happiness. They
work for happiness, they live for happiness. Thus everyone is servant
of happiness because just as any servant works for his boss, all
souls have only happiness to work for.
Happiness is God and hence it automatically
follows that everyone is servant to God.
This what Hindu claims 'All the living beings and
non living beings are servant to God.'
Gaurang Mahaprabhu says, 'The nature of soul is
eternal servant to Krishn.'
Another view is God is the soul of soul. Because
it is only through him we get all the energy that we need to do the
work, to think, to see, to smell, to hear and so on.
All the the body, all the senses, mind, intellect
work continuously to please 'I' which is soul. For example eyes see
the objects to make 'I' happy, ear hears to keep 'I' happy. Likewise
all senses do there activities to please soul. Hence all senses, mind
and intellect are servant to 'I'. They don't have their own
happiness.
Because God soul of soul, it but natural that soul
is servant to God. There is immense happiness in service to happiness
incarnate - Krishn.
