"The significance of Durga, Lakshmi and Saraswati has to be rightly understood. Three represent three kinds of potencies in man. Ichchaa Shakti (will power), Kriyaa Shakti (the power of action) and Jnana Shakti (the power of discrimination). Saraswati is manifested in man as the power of speech (Vaak). Durga is present in the form of dynamism (the power of action). Lakshmi is manifested in the form of will power. The body indicates "Kriyaa Shakti". The mind is the repository of"Ichchaa Shakti". The Atma is "Jnana Shakti". "Kriya Shakti" comes from the body, which is material. The power that activates the body, which is inert and makes it vibrant, is "Ichchaa Shakti". The power that induces the vibrations of'khchaa Shakti" is "Jnana Shakti" which causes radiation (of energy). These three are represented by the Mantra "OM Bhur-Bhuvah-Svah". "Bhu" represents Bhu-loka (earth). "Bhuvah." represents the life-force (also means conscience of man), "Svah" represents the power of radiation. All the three are present in man. Thus, Durga, Lakshmi and Saraswati dwell in the human heart."
