“NAM” is a Sanskrit word, which is usually translated as “name”. In this case the principle of this meditation that has an incredible importance is reduced to only repetition of a name (or the names) of God.
But in reality the meaning of this word is more profound and in the spiritual practice it means “description” — a sequential “actualization” for oneself of the components of the multidimensional structure of the Absolute through placing the consciousness into each of them and then into the whole Absolute.
And the purpose of the “NAM-meditation” is for seekers to distribute the concentration of themselves in more and more subtle manifestations of the Absolute — down to the Creator in His Abode — in order to habituate themselves to be in these states and to gradually increase their personal power.
