Service does not mean I do what I want, when I want. Sevice means, I do whatever makes Krishna happy.
Become united with one purpose and serve Hari.
Those who perform assorted religious activities can not serve the Supreme Personality of Godhead.
Everything is just meaningless, useless if it is not engaged in the service of the Lord.
If you go on serving simply, Krishna will give you everything.
In the transcendental loving service of the Lord, it does not matter whether we are working, cooking, painting, writing, chanting, or whatever. They are all the same. There are no such distinctions of higher and lower on the transcendental platform. The important thing is that we are engaging our time and energy in the service of the Lord. After all, we are so tiny, what can we do? Krishna sees simply that this time is being spent in His service.
