|Bhai Sahib Jeevan Singh Jee combing his Kesh|
ਗੁਰਮੁਖਿ ਰੋਮਿ ਰੋਮਿ ਹਰਿ ਧਿਆਵੈ ||
gurmukh rom rom har dhiaavai.
The Gurmukh meditates on the Lord with every hair of his body.
(Raamkalee M:1, 941)
Bhai Sahib said when you look after your Kesh (hair) properly they act as conductors of Naam current. Your Kesh on the head connects you to the sky and above. Your daarhi (beard) connects you to the ground and below. Your moustache connects you to the world around you. When these currents join the Naam feels like electric current going through your body.
