Do not wait for invitation. Volunteer yourself for the Guru’s service. Serve your Guru humbly, willingly, unquestioningly, unassumingly, ungrudgingly, untiringly and lovingly. The more your energy you spend in serving your Guru, the more the divine energy will flow into you. He who serves the Guru serves the whole world. Serve the Guru without selfish ends. Scrutinise your inner motives while doing service to the Guru. Service must be done to the Guru without expectation of name, fame, power, wealth, etc.
