 The book received mixed to positive responses from critics. R Krishna from Daily News and Analysis gave a positive review for the book. He observed that the criticism in the second book regarding bad editing and writing has been polished in The Oath of the Vayuputras. He complimented the fact that philosophical discussions in the book is rightly balanced by action sequences, commending the way in which Sati's fight with the assassins is described. Krishna concluded that the different characters of the book make it a good reading and a fitting ending to the series. Phorum Dalal from Mid Day praised the urban dialect used by Shiva in the book and felt that Tripathi's grip on the whole story is steady and has the reader's undivided attention, ultimately "giving the Trilogy an end it deserves". Sanjeev Sanyal from Business Standard gave a neutral review saying that although the fast-paced and easy style from the earlier books has been retained, it is evident if one goes back and rereads the first few pages of The Immortals of Meluha that Tripathi has become much more comfortable and confident of his writing. "Of course, those whose literary tastes have not outgrown Wren and Martin will still find fault with his use of the English language. For the rest of us, it is delightful to see how Tripathi applies simple language to evoke great battle scenes and extraordinary landscapes".
