When service is rendered in a selfless spirit it always benefits the Karmayogin, although he himself does not do it for the sake of any reward or result.
There is no doubt that even when he renders selfless service unintelligently he derives some spiritual benefit thereby, but in doing so he cannot avoid causing much unnecessary suffering to others.
However, when he renders selfless service with spiritual understanding it not only confers spiritual benefit upon himself, but also promotes the material and spiritual well-being of others involved.
Selfless service must be based upon understanding if it is to be an unmixed boon for all concerned.
