There often is an ecstatic resonance between some gurus and some students. The Shakti takes different forms with each. Each guru/student coupling is unique. For some it is constant ecstasies. For some, an always abiding Love. For some, constant orgasms in the heart or genitals. For some it is felt as deep peace. For some it is forgetfulness. For some, emptiness. For some it is grace, forgiveness, or energetic beingness. But when you get near YOUR teacher, something flows in you so that you know you are at home.
The manifestations of the Shakti are always changing. No one can tell you how it will be for you, even the teacher. Each day God, Guru and Self are experienced in different ways by That which lies beyond experience and non-experience. Those who would deny the Guru/Chela relationship as stupid or quaint or outdated religiosity do so because they have not yet found their teacher, and maybe never will. Nisargadatta said there are many who resist teachers, and for them it is best for all not to have any.
