In Rigveda(RV 7.59.12) is given the Mahamrtyunjaya mantra which states that Lord Siva can award liberation just as a gardener frees a ripened cucumber from its creeper. However Srila Prabhupada in Bhagavad-Gita As It Is very clearly states that Lord Siva is under the influence of maya so it is not possible for him to release the conditioned soul from the clutches of maya (Chap 7 Verse 15 purport). How can this be reconciled?
