Japji Sahib Commentary/ Translated by Master Teja Singh
By listening to the Divine name and drinking it deep in their minds, Shiv, Brahma, and Indra have attained their high dignities. Even a degraded person, if he begins singing His praises in love, becomes pure, and people begin praising him. By listening attentively to the Divine name and its praise one learns all Yoga devices (Pranayama and Samadhi) and comes to know the hidden secrets of the body, and the intricacy of its various veins and arteries. One comes to realise the essence of Truth contained in the six shastras, twenty-seven simrities, and the four vedas.
Note:-The final source of all knowledge is the human mind. The more it is illumined the higher the truth realised by it. A man who realises the Divine within, the fountain head of all knowledge, develops a direct power of intuition, and becomes at-one with the Divine Law. Thus he rises above all error and practises in his daily life the principles of Truth contained in the holy books.
Sayeth Nanak, His devotees who meditate on His name and drink in deep the nectar of the Divine life within, are filled with ecstacy and their faces beam with the Divine joy. No pain or sin can touch them They rise above all pain and sin.
