First of all sorry for the late reply. And I think this is the best answer ti your question:
This is a serious issue. The number of sikhs are decreasing in Punjab, India due to several factors:
1- Many people from outside Punjab are migrating there and multiplying very faster than Sikhs.
2- Sikhs are migrating to UK , Canada and other countries.
Sikhs (especially those living in Punjab) should have at-least 3 children in my opinion and ensure that each one of them becomes a gursikh.
But the above two issues aren’t too serious in my opinion. Sikhs comprise 60 percent of Punjab’s population. But living in Punjab- it doesn’t look like. In the streets or roads or in public places, Sikhs often look outnumbered. And the main reason is that lots and lots of Sikh youths are cutting their hair and abandoning Sikh values and heritage. They are murdering the rich and invaluable heritage and history of Sikhism.This is a very serious issue. I read in a monthly magazine about Sikhism - Sikh review an year ago that 65 percent of Sikhs in India are not saabat soorat (or natural) as they should be according to the their religion. I wasn’t too surprised to read this. 65 percent of Sikhs have cut their hair (at least beard).
Stop cutting hair sikh men and women, and get to know about their significance and the reason for keeping hair. And the saabat soorat sikhs should spread awareness about this issue, instead of looking at it casually.
