Is There a Shiva Mantra?

Before the initiation, you have to ask the Guru whether the Guru will be willing to give a Shiva mantra or not. Paru says, will Guru give the mantra Dixa as well suggest Istadheva to meditate upon? At that level, this entire universe is one reality. Everybody is one with you or you are one with everybody and everything. So that is that oneness. You can let go of all thinking at that level.
