Detachment

Detachment may be learned through service .Until it is acquired and one is able to renounce emotional ties to one's labor , no meditation is possible .As the detachment increases , it becomes easier and easier to disassociate from activities .Then when the eyes are closed , the mind will remain unperturbed; it has been trained to focus inwardly at all times .Others may see a Karma Yogi and think he is just another person working; they will not know the secret of his inner peace .
