All Hindu deities represent cosmic energies that are part of the Divine Universal Energy or the Supreme God-head.
In this regard, Ganesh represents the energy that is capable of removing obstacles and obstructions. Due to this, he is revered and paid obeisance before starting any auspicious or important work. His blessings are sought before starting travel to ensure safe, smooth journey and successful completion of work.
According to mythology, Ganesh is the second son of the deities- Shiva and Parvati. Here the concept of ‘son’ is used to indicate the product or an effective outcome.
The energy of this action of creation (kinetic or action energy) is their first son- Karthikeya. Thus Shiva and Shakti together create this form-world as we know.
Their second son is Ganesh. Thus his energy is of prime importance in this created (manifested) world and he is considered as a ruling-leader of the masses. It is due to this leadership position that Ganesh is revered before starting any important task. He is considered as the prime energy of importance in our material world for special occasions as well as day to day existence.
Ganesh’s two consorts are Buddhi (Intellect) and Siddhi (Accomplishment). Typically his consort Buddhi is also addressed as Riddhi which is Abundance or Affluence. This is to indicate that the energy of Ganesh is the governing energy behind intelligence, abundance, affluence and accomplishment.
Joyous benevolent Ganesh is revered by millions worldwide across many cultures and countries. He comes to the aid of anyone who requests through prayers for help and guidance. It could be in the form of daily prayers or to ask for obstructions & obstacles to be cleared before starting a special venture or before starting on a journey for its successful completion.
As the ruling energy- i.e. the Leader of the Masses- Ganapati is always willing to help and benefit anyone who seeks his guidance.
