Premanand Maharaj Ji
Is seva also bhajan if I can't chant the Naam while serving?
Seva itself is bhajan
Naam, vani (devotional verses) and seva are the three main forms of worship, and being engaged in any one of them is bhajan. So seva is bhajan too, and you should not be discontented if you can't chant while serving.
If you are engaged in even one of the three, your bhajan is happening. If we are in seva, whose seva are we doing? We are doing Shri Ji's seva, aren't we?
