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.
When one's mind is attached to Krishna, one can fulfill the mission of life in one human birth. If one misses this opportunity, one does not know where he is going, how long he will remain in the cycle of birth and death and when he will achieve the human form of life and the chance to return home, back to Godhead. The most intelligent person, therefore, uses every moment of his life to render loving service to the Lord.
Our skills can be applied to serve Krishna.
You cannot artificially stop the functioning of the senses but if you engage the senses in the service of the Lord, to please the Lord, then you will become very happy.
