The Guru points in the right direction. He/she points towards the inner self. This self is full of bliss. The course towards this self leads through the mind and the emotions. Many obstacles reside in the mind and the emotions. Kundalini Shakti moves through the mind and the emotions and dissolves these obstacles.
The secret is that the outer
Guru and the inner Kundalini are really one and the same. The Guru
sparks the Kundalini energy and directs it towards its goal, which is
the center of a person's existence, a person's inner self.
