Shabd is found within the body
The Shabd or Naam is heard and realized by research within the human body.
If one searches the township of the body, through the Shabd one gains the nine treasures of Naam1.
Ramkali M2, 910-1
It is by turning inwards and purifying the mind that the Lord is found.
By purifying the mind one crosses this world. This is done by reflecting on the quintessence of the self. They who serve the Master enjoy peace, and the Shabd pervades their inner self.
Ramkali M1, 908-2
Guru Nanak telling us about the location of the Shabd says that it can be heard beyond Ida, Pingla and Sushmana, through the Grace of the Master.
He knows Ida, Pingla and Sushmana. He sees for himself the Unseeable. Oh Nanak, the True Master takes him beyond them, He merges him in the Sound.
Ramkali M1, 944-18
Footnote: 1) The nine Spiritual Treasures are:
1. Bharosa – Faith. A deep faith in the Lord and dependence of the Lord. The firm faith in Waheguru is the first and foremost experience of a practitioner of Naam.
2. Leenta – An absolute attachment to the Lord.
3. Santokh – Contentment.
4. Bairaag – Detachment – from worldly possessions.
5. Hukam – Acceptance of and total surrender to the will of the Almighty.
6. Sahaj – Equilibrium and Equipoise of the mind.
7. Anand – Perpetual delight and permanant joy.
8. Vismaad – Ecstasy. Joy and wonderment.
9. Nadar – An awakened soul considers the Almighty as the prime reason of his attainments and that his own efforts means nothing. This attitude keeps ego far away from the person.
