Which yajna was it which was performed by Prajapati Daksha in which he didn't invite Lord Shiva and suffered with consecutive events ?
Which yajna was it which was performed by Prajapati Daksha in which he didn't invite Lord Shiva ?
The answer is provided in Mahabharata-Shanti Parva-Moksha Dharma Parva- Chapter-283 , where this story of Daksha yajna is narriated by Maharshi Veda Vyasa. When Goddess Uma came to know about all the gods leaving for Daksha Prajapatis yajna , she was curious and asked lord Shiva about that. Then Lord Mahadeva himself answered to Devi Uma that Daksha prajapati is performing Ashwamedha yajna. Following is the shloka of that conversation.
दक्षो नाम महाभागो प्रजानां पतिरुत्तम : |
हयमेधेन यजते तत्र यान्ति दिवौकस: || 24 ||
P. 311 - Maheswara said, 'O lady that art highly blessed, the excellent Prajapati Daksha is adoring the gods in a Horse-sacrifice. These denizens of heaven are proceeding even thither.
So Daksha Prajapati was performing Ashwamdha yajna at the time , when devi Uma asked Mahadeva about the Yajna and why he is not invited to the Yajna .
Here is Hindi Translation with Shlokas.
It seems that the Yajna is called "Devi Yajna".
As per Devi Bhagavatam:
He is not to return any more. He who bathes in all the Tîrthas and makes a journey round the whole world, gets Nirvâna. He is not reborn. He who performs the Horse-Sacrifice in this holy land Bhârata enjoys half the Indraship for as many years as there are hairs on the body of the horse. He who performs a Râjasûya Sacrifice, gets four times the above result. Of all the sacrifices, the Devî Yajñâ, or the Sacrifice before the Devî is the Best. O Fair One! Of old, Visnu, Brahmâ, Indra and when Tripurâsura was killed, Mahâ Deva did such a sacrifice. O Beautiful One! This sacrifice before the S’akti is the highest and best of all the sacrifices. There is nothing like this in the three worlds. This Great Sacrifice was done of yore by Daksa when he collected abundant sacrificial materials of all sorts. And a quarrel ensued on this account between Daksa and S’ankara. The Brâhmins conducting the sacrifice cursed the Nandî and others. And Nandî cursed the Brâhmanas. Mahâdeva, therefore, disallowed the going on of sacrifice and brought it to a dead stop. Of yore the Prajâpati Daksa did this Devî Yajñâ; it was done also by Dharma, Kas’yapa; Ananta, Kardama, Svâyambhuva Manu, his son Priyavrata, S’iva, Sanat Kumâra, Kapila and Dhruva
Book 9, Chapter 30
Therefore, it is the Devi Yajna which Daksha was performing and which was eventually destroyed by Lord Shiva's troops.
