Brahman means boundless or the ultimate reality. Ananda means the blissfulness or ecstasy of the Creator, and Swaroopa is the form or image of the ecstasy of the Creator.
When we consecrate a certain set of sounds, it is done with the intention that a large part of you will become absolute stillness, but you will retain the liveliness of life around you. And slowly, this becomes like a coating, like a shield around you. A cocoon of a certain energy. So Brahmananda Swaroopa can be used as a raiment that you wear; it is a clothing that you wear all the time. This chant is more like your clothing, this is not a seed. If you keep on chanting with sufficient involvement, it will be around you. If your life breath becomes this, people can feel it.
