The path is otherwise known as Nishkaam, which means selfless worship of the divine—the One and the Only, the One without any other—known in the world today variously as God, Allah, Om, Aum, Adonai, Khuda, Waheguru, and so on.
In all beings in the Lord’s Creation, there exist two hearts. One is the physical heart that we all know on the left side of the chest. The other is the Principal Heart, the location of which is pointed out by the guru at the time of initiation. This is the same heart that is referred to by the enlightened master, Buddha, in his mantra 'Om Mani Padme Huum'. (The Jewel in the Lotus of the Heart.)
The same heart is pointed to by other enlightened masters in their teachings.
A sincere seeker starts off by expressing his or her genuine spiritual thirst to the guru. The guru, if and when the right time comes, initiates the seeker by pointing out the Principal Heart in the seeker’s body, and giving the seeker a name of the divine to repeat selflessly. This is called the Guru Mantra. The name given by the guru can be any of the names of the divine. The student meditates on this Guru Mantra every day selflessly while concentrating on the Principal Heart, and without expectations of any kind in return for the meditation.
At the end of the current lifetime, conditions are created by the divine, such that the student is born again as a human in a place where she again gets the same guru or another guru of the same path. The guru then initiates the student again in the new lifetime. If this selfless meditation is done over several lifetimes, a time comes when the quantity and quality set by God is reached, and God himself descends into the body of this person. The person has now reached the state of enlightenment. This is the last lifetime of this person as a human or as any physical creature. After this, the person is never born and never dies. The person is permanently in the state of bliss.
