Explanation:

The Guru Granth Sahib begins with the word "Ek Onkar" – The All Pervading Being. From this Word to the tenth Word “Gur-parshad” is called the Mool Mantra. After this is the rest of the composition called the Japji composed by Guru Nanak Dev. This comprises 38 Pauris or stanzas, a Prologue and an Epilogue. This is one of the morning prayer of the Sikhs.

The next composition has two parts - (1) "So Dar" and (2) "So Purkh". The Bani, "So Dar" contains 5 Shabads and "So Purkh" contains 4 Shabads. This form most of the evening prayer of the Sikhs and is called the Rehras. After this is the Bani called Sohila (full name, Kirtan Sohila), which contains 5 Shabads and is the bed-time prayer.
Anand Sahib: This Bani is part of the Nitnem (prayers) which are read by Amritdhari Sikhs in the morning. This Bani was written by Guru Amar Das, the third Guru of the Sikhs and forms part of the 5 Banis that are recited daily by baptised Sikhs. The Bani appears on pages 917 to 922 of Guru Granth Sahib, the Sikh Holy Scriptures.

Jaap Sahib is the morning prayer of the Sikhs. The beaded prayers were composed by the Tenth Sikh Guru, Guru Gobind Singh and is found at the start of the Sikh scripture Dasam Granth.
