Please keep note this very important Divine Truth, that just by doing Matha Tekna to Shri Guru Granth Sahib Ji you are not automatically accepted as a true disciple and you are not authorized to call it your Guru. In the real divine sense, Shri Guru Granth Sahib Ji will only become your Guru when and if you follow GurBani in your daily life by living according to the GurMat within it. Nothing less then that will make you a true disciple of the Guru. Doing GurBani in your daily life will make you a true disciple and not just by doing Matha Tekna or reading or listening to GurBani. Becoming GurBani by doing GurBani is the key to success and this is the only way to respect Shri Guru Granth Sahib as the Guru.
