Anand Sahib is the “Song of Bliss” by Guru Amar Das consisting of 40 hymns*.
* Many people incorrectly read the first 5 hymns of Anand Sahib and then jump to the 40th hymn. The 40 hymns are known as “Pauris” or “Steps” because just like a ladder, each step must be climbed in order to reach the next step. The effect of the Anand Sahib is lost by skipping to the 40th step after reading just 5 steps. Instead, one should either read just the first 5 hymns or read all of the 40.
