Philosophical concept of God in Hindu Dharma

Hindu Dharma is believed to accept the existence of several Gods or deities.But in reality it accepts only one God, the Supreme God.

Brahma, Vishnu and Shiva. are not three independent and separate deities, but three different aspects of the same Supreme God, while engaged in the processes of creation, sustenance and destruction of the universe, in that order. It is similar to the role played by the same person as the father at home, as the boss in the office and as a customer in a shop. Other deities also should be considered in the same light, as different aspects of the Supreme God, manifesting themselves for specific purposes.
The powers of these deities which are inseparable from them – just as the power of fire to burn can not be separated from fire itself. This power is conceived in the form of their consorts, Sarasvati, Parvati (or Sakti) and Lakshmi.

This is not to say that these deities are imaginary creations. All of them, without exception, are different modes and aspects of Paramatman, the Supreme Self or God.
