In this Katha clip, Sant Giani Hari Singh (Randhawe Wale) offers a detailed explanation of the preface to the Shabad "Maranai Kee Chinthaa Nehee Jeevan Kee Nehee Aas," found on Ang 20 of Sri Guru Granth Sahib Ji Maharaj. This Shabad was spoken by Sri Guru Nanak Sahib Ji to Ajita Randhawa.
ਮਰਣੈ ਕੀ ਚਿੰਤਾ ਨਹੀ ਜੀਵਣ ਕੀ ਨਹੀ ਆਸ ॥
I have no worry about dying, and no hope of living.
