Significance of the Spiritual Name
Let me give the definitions of the words engram or samskara and mantra.
Any word which is inscribed in your inner space, which binds you, which suffocates you, which brings you down in your consciousness, is a samskara or an engram.
Any word inscribed in your inner space which liberates you, which takes you to higher consciousness, which takes you to a more joyful and blissful state is a mantra.
Mantra and samskara are almost the same, but samskara binds you, while mantra liberates you. Mantra is the antidote for samskara. If you are given your name by a person who is yet to get enlightened, who still lives in unconsciousess, then your name can become a bondage for you. If you are named by an enlightened being, by a person who lives in superconsciousness, your name is a method or technique to liberate you. Your very name can be used as a technique for enlightenment.
If your spiritual name can be used in the social setup in which you are living, that is the best thing, because the whole day from morning until night, either you will be using the name or someone else will be using the name to address you. When this happens, understand that every moment becomes a spiritual practice for you! Your name is the right word from an enlightened master, given to you as a technique. Every time it is repeated, you are entering into the zones of higher consciousness. Every time you remember the meaning of it, you move to a different plane.
