Veerji,
Perhaps, Bernard Shaw understood something our misled brothers and sisters don't. This incident reminded me of Dr. Rabindarnath Tagore. He was at a kavi(poet) sammelan (gathering/conference) when he ran into into a Patit. This person was a budding poet and in complete awe of Dr. Tagore. He was eagerly looking forward to meet him. He told Dr. Tagore how much he liked his poems and his overall work in general. Dr. Tagore said thank you, but I have a question for you.
Dr. Tagore: You use the last name as Singh, are you a Sikh?
Budding Poet: Yes, Dr Sahib, I am a Sikh.
Dr. Tagore: Do you read do any Baanis of your Gurus?
Budding Poet: Yes, I do Siri Japji Sahib everyday in the morning.
Dr. Tagore:
I would just like to tell you that I read the great baani of Siri Japji Sahib only once in my life and after that never touched razor again.Moral of the above story: Dr. Tagore being a great poet had deeper understanding than most. He felt the depth of Gurbani and as a mark of respect to Guru Sahib's hukam chose to never cut his beard again. In comparison, our misled brothers and sisters are often found questioning the Hukam itself.
Guru Sahib kirpa karan.
