Places of pilgrimage in Sikhism

Hardeep — Mon, 21 Jan 2013 10:58:46 +0000

Recently returned from a visit to Sachkhand Sri Hazur Sahib. This was the last residing place for the Tenth Guru. The journey was enjoyable, and the time spent very gainfully. I wished I could stay a few more days. On the way, I spent some time thinking about what would constitute the most important place [...]

Holi

Hardeep — Fri, 09 Mar 2012 01:57:15 +0000

I have written about many Indian festivals, but never about Holi. It is the Hindu festival of colours, much like Diwali being the festival of lights. For Sikhism, colours are strong depictions of mental state. There is no physical relevance to colours. A Sikh is expected to wear ordinary clothes that do not attract attention. [...]

Releasing: Gurbani search for mobile

Hardeep — Wed, 21 Dec 2011 01:36:47 +0000

Gurbani searching on the mobile used to be tough. Symbian and Android phones do not support Unicode with Indic support, which is required to use gurmukhi websites. Opera Mini allowed us to read gurbani, but entering search text is a different matter. I have developed a web page that allows you to do this, but [...]

Guru Hargobind Sahib Ji, sixth Sikh Guru emerging from Gwalior Fort where he was imprisoned by Emperor Jahangir. Along with him, 52 Hindu chieftains were also released, on request from the Guru. Sikhs celebrate Diwali festival as “Bandi Chhor Diwas” because the Guru reached Amritsar back on the Diwali day. For the full story visit [...]
