One may have many teachers, but only one guru, who remains as one's guru even in many different lives, until the disciple reaches the final goal of emancipation in God. You must remember this, once that relationship is formed.
The purpose of the guru is not to weaken your will...
It takes a long time-many incarnations of right action, good company, help of the guru, self-awakening, wisdom, and meditation-for man to regain his soul consciousness of immortality. To reach this state of Self-realization, each man must practice meditation to transfer his consciousness from the limited body to the unlimited sphere of joy felt in meditation.
