We have Mantras to Invoke the blessings of the Lord. Saraswati the goddess of knowledge is the deity invoked through this mantra. Knowledge is not separate from prosperity and wealth etc. So the mantra has "beejaksharas" ( various aspects of the power of the Lord is coded and it becomes complete mantra for the required benifit of chanting it ) To do it continuously is "akhanda nama japa" .
