In Vedic literature, there are hymns in praise of different Lords which are called Mantras. Who are these Gods? They are the ones who give us material benefits in life such as wealth, prosperity, education, marital bliss, happiness etc. and also spiritual strength to get off the cycle of rebirth.

Lord Ganesha (elephant faced God) is always worshipped before starting any Pooja or Homa. Lord Ganesha removes all obstacles. Lord Ganesha is also known as Vigneshwara [vigna + Eswara] which means the lord who removes all obstructions (Vighna).

There are many mantras to propitiate Lord Ganesha. By and large there are 56 different postures and mantras for Lord Vinayaka. In Shilpa sastra, all the 56 positions are described elaborately.

The following Ganapathy Homas are performed generally by many even now.

Ganapathy Homa should be performed in the early morning and Poornahuthi to be offered during sunrise, unless any other time is specifically mentioned to suit the particular purpose.

There are two ways of performing Homas, Vedic and Tantra.

In the Vedic way of Homa, all rituals are performed as per Vedic texts. In tantra, sometimes Vama prayog is also done to safeguard the native from enemies and adversaries. It also produces adverse effect on enemies Normally only Vedic way of Homas are performed.

To perform Ganapathy Homa the following materials are essential.
Ghee, Modhaka (a kind of sweet prepared with coconut, gur and rice flour or wheat flour), durva (a kind of grass).

Mahaganapathy Homa is performed with Ashta Dravya (a mixture of eight materials)
1.Coconut, 2.Banana, 3.Honey, 4.Sugarcane, 5.Ghee, 6.Modhaka, 7.Jaggery, 8.Puffed rice.

Ganapathyatharvashirsha is in praise of Lord Ganesha.
(Please refer Shri Mahaganapathya Atharva seersham) This mantra is recited normally while performing Ganapathy Homa. The benefits of the mantras are described in these last three mantras.

By chanting these mantras, one can live peacefully, without any hindrance. He who wants to become a good orator should do Abhishekam to Lord Vinayaka with this mantra. A man in need should perform Homa by durva (A kind of grass). A man seeking good memory and reputation should do Homa with puffed paddy. He who desires prosperity should perform Homa with 1000 modakha. He who performs Ganapathy Homa with ghee and samit (a kind of branch of tree) will get everything he desires.

After that he will not face any hindrance and all his sins will be washed off. All his desires will be fulfilled. This is what of Veda and Upanishad say.
