Control of the breath and positioning of the tongue, focusing at the third eye and wearing
rosary of Ttulsi beads, are all obtained (by awakening) the Divine Grace Within (sggs 973).

We know the location of two eyes in the physical body; for their location is outer. But this so called third-eye is inner, which we cannot see because there is no physical location of it. The other most important and subtle inner position is the "cave of the heart". The third-eye, a figurative speech, is an another subtle inner position, similar to the Tenth Gate (Dasam Duaar). All these inner subtle states are intimately connected or essentially one and the same. The third-eye is where light or consciousness can be concentrated. In meditation some may attempt to "see" through it. Also called by other names such as subtle center of superconsciousness, spiritual eye, "ਦਿਬ ਦ੍ਰਿਸਟਿ" - Dib Drisati, Dib Disati, Dibya Drishti, ਤੀਜਾ ਨੇਤ੍ਰ, etc.) command center, Divine Darshan (a soul that has had vision of the Supreme Being), etc., many kinds of experiences are associated with this: symbolic and imaginable vision.

Andaru kholai dib disati dekhai mukti bhandaaraa: One who is a buyer of the Divine (Unconditioned Reality), finds it, and obtains the jewel of contemplation.

Simply put: the inner or third-eye is a state of "no ego" (no Haume ), "Shabad-Surti" (God Consciousness), realization of Truth, Transcending of Maya (illusion), freedom from the darkness of ignorance, spiritual Wisdom, inner (spiritual) strength and maturity, Sahaj-Avasthaa, Jeevanmukti, and so on. It is an eye of the True Knowledge or Infinite Wisdom (Self-knowledge or Aatam-Giaan): the state of always being "awakened" within. It is the experience of the True Self ("Joti-Svaroopa"), the mind shunned ("Sunn-Samaadhi") of all thought-wanderings (ego), realization of All-pervasiveness of One Universal Consciousness, being established in Witnessing Consciousness, being established in the Realm of Truth (Sach Khand), blossoming of the Soul to the Source, the state of All-knowing, the Cosmic Mind — Pure, Clear, Unconditioned, Undisturbed, and so on. It cannot be experienced through reading books. Also, it cannot be made to an order or given to someone as a gift. For it is totally experiential and not conceptual. Therefore, it is not something conveyed in words. It is pure experience, the state in which one sees everything as his own Self. Experience of this state does not mean you close the other two eyes. Spiritual path is difficult like walking on a "two-edged sword", to succeed at this, we need to awaken within the guidance and grace of the Guru or God. These have to be earned, which implies that there has to be right effort made at appropriate time. Therefore, it's an arduous journey of selflessness, commitment and sacrifice. Such inner renunciation requires an iron determination to change our life's direction from the worldly to the spiritual. Unfortunately, the majority of us are unable to sustain the same spirit for too long.

Thus, the third-eye is not a physical eye. If one were to develop a physical third-eye on his or her body, that person will be in a zoo or museum! In nutshell, this third-eye is a state where the duality (Doojaa Bhaava) has disappeared. As such, it has nothing to do with stuff like seeing a bright light, hearing voices back or feeling head getting hot, etc.

One can see material objects with the help of the outer eyes of the physical body. But we cannot experience the state of God Consciousness with material eyes or any other bodily senses. To realize God Consciousness, we need to develop the new inner eye called third-eye. In other words the outer two eyes need to become one eye called the third-eye. Then duality (Maya or Doojaa Bhaav), ego or doubts disappear and one beholds the Vision of Oneness of the entire creation. In other words, when our external eyes become blind to the world of plurality or falsehood, even if they are opened, that is when the third-eye is opened. But according to the Gurbani, such spiritual beings (Gurmukhs) who are free of the ugliness of false ego-sense or Haume is very "rare" in the world. Rest of us just talk and create troubles.

  • ਤਤ ਸਮਦਰਸੀ ਸੰਤਹੁ ਕੋਈ ਕੋਟਿ ਮੰਧਾਹੀ ॥: Tat samadarasee santahu koee koti mandhaahee: One who sees the essence of reality with impartial vision, O Saints, is very rare-one among millions (sggs 51)
  • ਜਲਨਿ ਬੁਝੀ ਦਰਸੁ ਪਾਇਆ ਬਿਨਸੇ ਮਾਇਆ ਧ੍ਰੋਹ ਜੀਉ ॥: Jalan bujhee daras paaiaa binase Maya dhroh jeeou: My burning desires were quenched, when I obtained the Divine Vision of; the fraudulent illusion of Maya is gone (sggs 929).
  • ਗੁਰਮੁਖਿ ਵਿਰਲੀ ਏਕੋ ਜਾਣਿਆ ॥: Gurmukh viralee eaeko jaaniaa: Rare indeed is he who as Gurmukh realizes the One Lord (sggs 905).

Third-eye is in an inward state. It begins to open when the Self-Unfoldment takes place. Meditation ( Jap or Naam-Simran) is the technique to open the inner eye. It requires sincere self-efforts, and Saadh- Sangat (Holy Company) to make sure the self-efforts bear the right fruits. The Gurbani urges us to focus on the Name of the One Divine, which helps awaken the Divine Grace within. Which, in turn, bestows on the seeker everything. In other words, once we become the Gurmukhs (Self-Realized, pure or egoless beings, Brahm Giaanee, etc.), all other things are automatically added on to the seeker of Truth.
