This is a sequel to a volume published in 2011 by OUP under the title The Ubiquitous Siva: Somananda's Sivad¿¿¿i and his Tantric Interlocutors. The present volume presents the fourth chapter of the Sivad¿¿¿i and Sivad¿¿¿iv¿tti and addresses a fresh set of issues that engage a distinct family of opposing schools and authors of mainstream Indian philosophical traditions. Somananda challenges his philosophical interlocutors with a single over-arching argument: he suggests that their views cannot cohere-they cannot be explained logically-unless their authors accept the Saiva non-duality for which he advocates. The Ubiquitous Siva Volume II offers the first English translation, critical edition, and commentary of Chapter Four of the Sivad¿¿¿i and Sivad¿¿¿iv¿tti.
