S'rî Sukta - God appears in the form of S'rî Vishnu to uphold and protect the world. All action by Lord Vishnu is performed by His S'akti Lakshmî. She is the mother aspect of creation and the nourisher of the three worlds. Her description appears in the S'rî Sukta, where she is glorified. In reality, there is no difference between Lord Vishnu (the one who holds the power of action) and Lakshmî (His S'akti who actually performs the action). Lakshmî is then the presiding deity of all Divine manifestation.

S'akti - S'akti is intelligent energy. When something is s'akti activated, it will be alive in a real sense because some intelligent energy is attached to it. Consider the difference between a living person and a dead body - that is the difference between an object that is s'akti activated and one that is not.
