drkhalsa ji,
Most of such surnames arise from their native villages. Also some people used to have takkhalus, which very well applies to the original person who is poet/writer etc, but then when his kids keep that as their own surname, that is again an example of inappropriateness.
Main thing which I have realized is - being born to a sikh parents, we assume lot of things. Or perhaps even give a little thought about significance of most of things, which reduces to an activitiy - ritual like. There is where problem begins.
Also, most of the times, I am getting of the opinion that, instead of keep on talking about Gurubani, doing analyses, applying our own wisdom, comparing with other religions etc, we need to extract the Gurubani teachings and apply those learnings in our daily life - that would be something best we could perform in our life as a sikh.
I am just learning with the help of people on this forum. But more and more I read these posts, a tendency to withdraw from these discussions arises, and a passion to read more and more from Guru Sahib ji comes up. Because there is what all the learning is there, and we need to be having a receptive mind as a child and analysing and passionate as an adult, and wise (jo doosre nu naam japaunde hun) as our elder ones.
Regards.
