* Being in someone's service: This could mean working for someone, assisting them, or being their servant. For example, "मैं आपकी सेवा में हूँ" (Main aapki seva mein hoon) translates to "I am at your service".
* Being at someone's disposal: This can indicate availability and willingness to help.
* Being dedicated to a cause or service: This could refer to volunteering or dedicating time to a particular cause.
It's important to note that "seva" itself carries a broader meaning than just "service". It often implies a sense of selfless dedication and compassion in serving others.
The specific meaning of "seva main" would depend on the context in which it is used.
