Baba Nam Kevalam
Baba means "my most beloved One", Nam means "name of" or "to identify with", and Kevalam means "only". So the meaning of the mantra is "My most Beloved is the only One." The ideation is: "Everywhere I look, in everything I hear, feel, see, taste and smell, I perceive that one Supreme Consciousness which pervades all things."
Kiirtan is the singing of a mantra aloud while ideating on the Supreme Being. It inculcates the feeling of bliss and prepares the mind for meditation, because in performing it all the motor and sensory organs are engaged and directed towards the Supreme. It can be done anywhere, any time, but the best time is just before meditation.
Chanting the mantra out loud before meditation is called "kiirtan." It is extremely beneficial and makes meditation much easier. Its a sort of a halfway step. The mind stays focused only on the mantra, but all the senses are not focused inwardly--we are still singing and listening. It helps slow breathing (through singing), helps fix the mantra in the mind, and on a subtler level, raises the vibration in the room.
