Sorath:
Satguru who resides in Waheguru (Brahm), meeting such Guru-conscious person (Guru Amar Das), and becoming one with him he too acquired all traits of Guru.
Through the blessings of Naam Simran of the principal Guru Satguru (Amar Das Ji), Guru Ram Das Ji too became prime Guru.
Dohra:
In the association of prime Guru (Guru Amar Das Ji) he too became Guru and found refuge in the holy feet of the Lord.
The Guru-conscious person whose name is Ram Das, by perpetual meditation on Lord's name, became Guru-oriented and virtuous (Satguru)
Channt:
Through God-conscious Guru Amar Das Ji and by the blessing of meditation on His name, the virtuous Ram Das emerged as Guru Ram Das (slave of the Lord).
Because of knowledge of Guru Shabad and consciously uniting with Him, Guru Ram Das became known as principal Guru.
The flame of a beacon lights up another lamp.
Thus Guru Ram Das became principal Guru through the blessings of Simran of Lord's name and his association with Guru Amar Das Ji. (5)
