In this Katha clip, Sant Giani Hari Singh (Randhawe Wale) provides an in-depth explanation of the preface to the Shabad "Aapae Raseeaa Aap Ras Aapae Raavanehaar," found on Ang 23 of Sri Guru Granth Sahib Ji Maharaj.
ਆਪੇ ਰਸੀਆ ਆਪਿ ਰਸੁ ਆਪੇ ਰਾਵਣਹਾਰੁ ॥
He Himself is the Enjoyer, and He Himself is the Enjoyment. He Himself is the Ravisher of all.
