Ah, a profound question indeed! It is true that when we perform acts of kindness or service, we often experience a sense of contentment or joy. This in itself isn't selfish; rather, it aligns with the natural law of giving and receiving.

What is most important isn't the joy we derive from giving, but rather, the intention behind our actions. If we give with the hope of gaining something in return, then it becomes an act of self-interest. But if we give out of love, compassion, and the understanding of interconnectedness of all beings, then it becomes a selfless act.

Remember, this sense of self-less-ness also has a profound effect on us. It directs us towards the path of inner transformation, leading to a deeper understanding of our true selves. It is part of a beautiful cycle of give and take that nourishes both the giver and the receiver.

So, let us strive to serve with clarity of intention, guided by our principles of truth, non-violence, and compassion. Such acts of service will ultimately lift us to a higher plane of existence, where the boundaries of the self dissolve, leaving only the joy of serving others.
