The word RAAM or RAAMu alone in Gurbaanee is the reference for HARi/Prabh/EKANKAAR only.Hundreds of times 'RAM' word is used in Gurbani. It's not necessary that it's for 'the king' Ram-Chandra. "RAM" is meant to someone who is merged in The Almighty "Ramya Hoya" / Merged in Almighty. So Kabir Ji obviously would not worship a body so his attention is towards the Almighty & all those who are merged in the Almighty/Akal Roopi Jeevs
Wherever in Gurbaneee ,the word RAAM found as reference for King Ram Chandra is only along with other names of that era like Ravan,Sita or Luxman.Such application of the word Ram makes clear about its reference.
