New Delhi :-Dhumraketu is God Ganesh.Ganesha took Avatara in each Yuga. Dhumraketu is one of his Four incarnations.In this Kaliyuga his Avatara name is Dhumraketu.
The Kridakhanda of the Ganesha Purana narrates the stories of four incarnations of Ganesha, each of which appeared in the four different yugas. The explanation of the incarnations of Ganesha is shown in the verses in the 132th chapter of Kridakhanda of Ganesha Purana’
The details Avatara in each yuga as follows:
1.Krita Yuga:
Mahotkata Vinayaka (Mahotkaţa Vināyaka), who has ten arms and a red complexion. Different sources list his mount (vāhana) as either an elephant or lion. He was born to Kashyapa (Kaśyapa) and Aditi in the Krita yuga. The name Kāśyapaḥ (descendant of Kaśyapa) for Ganesha refers to this incarnation. This incarnation killed the demon brothers Narantaka (Narāntaka) and Devantaka (Devāntaka), as well as the demon Dhumraksha (Dhūṃrākşa).
2.Treta Yuga:
Mayuresvara (Mayūreśvara), who has six arms and a white complexion. His mount is a peacock. He was born to Shiva and Parvati in the Treta yuga. He incarnates for the purpose of killing the demon Sindhu. At the end of this incarnation he gives his peacock mount to his younger brother Skanda, with whom the peacock mount is generally associated.
3.Dwapara Yuga:
Gajanana (Gajānana), who has four arms and was born with a red complexion. He has a mouse as his mount. He is born to Shiva and Parvati in the Dvapara yuga. He incarnates for the purpose of killing the demon Sindura (Sindūra), who was so-named due to his reddish-pink complexion.It is during this incarnation that Ganesha gives the discourse known as the Ganesha Gita to King Varenya.
4.Kaliyuga:
Dhumraketu (Dhūmraketu) is grey in colour, like ash or smoke (dhūmra). He has either two or four arms. He has a blue horse as his mount. He will come to end the decline of the Kali yuga. During this incarnation he kills numerous demons. Grimes notes that there is a parallel between this incarnation of Ganesha and the tenth and final incarnation of Vishnu, where he will ride upon the white horse Kalki. The other difference is, lord Gajanana tells Varenya that the whole universe and all the gods are created by Gajanana and ultimately everything will come back to him including the Gods like Bramha, Vishnu and Mahesha
