Different people belonging to different religions hang different things around their neck, hands, head or different parts of the body. How does it matter where and what are you hanging on your body?
“Have you seen the lord within yourself?” is the only important question.
However, let alone seeing the lord within themselves, people don’t even know that they are supposed to search for him inside. They don’t even know who lord is. Actually, the problem is not even that they don’t know about the lord; the problem is actually that they know a lot about the lord and whatever they know about the lord is wrong.
Gurbani says “Oh my friend! The lord exists within you. Till when will you keep searching outside? Till when? Come back to your source. Come back to your own self.”
