(The word Rama (ˈraːmɐ) appears in the Guru Granth Sahib more than 2,500 times.)
Some verses from guru granth sahib.

rAjA rAm nAmu morA braham giyAnu (Page 1159)
(The Name of Raja Ram is divine knowledge for me.)

jIvatu rAm ke guNa gA-i karahu kripA gopAl bIThule bisari na kabahi jA-i (Page 1223)
(I live by singing the praises of Rama. O Gopal, show grace unto me, that I may never forget You.)

rAm japahu ji-u aise aise dhrU prahilad japi-O hari jaise (Page 337)
(As Dhruv and Prahlad meditated on Hari, so do thou, o my self, contemplate on Rama.)

avilokau rAm ko mukhArbind khojat khojat ratanu pAio bisrI sabh cind caran kamal rIdai dhAri, utariA dukhu mand raj dhanu parvAru mere sarbaso gobind sAdh sangami lAbhu pAio nAnak phir na marand (Page 1304)
(I behold the lotus-like countenance of Rama's face. Searching and seeking, I have found the jewel of the Lord's Name and am rid of all anxiety. By enshrining the Lord's feet in my heart, my suffering and foulness is shed. Govind is my dominion, wealth, family and everything. Nanak says, in holy company, I have earned that after which there is no death.)

I came with it to describe the practise of following the Gurus teachings, worshipping Waheguru etc but also respecting and venerating figures like Shiv,Durga or Krishna
