If you experience profound transformation through a spiritual Master at this time in your life, honor the Master and stay devoted to the daily Sadhana into which the Master has initiated you. But don't assume that your Master is the only Master and his teaching is the only way. For this is the seed of fundamentalism & spiritual death. It has happened to some of the world's greatest religions.
Know that your experience is part of a wave of transformation sweeping the planet, blessing all who open to it, and it flows into humanity through mutiple rivulets and channels. A profound human flowering is occurring in the grace of many spiritual Masters today. This flowering in you and in others is the second coming of Christ-Consciousness.
If your path seems diminished by the realization that others are also flowering as you are, on other paths, then there is some weakness, some insecurity in your root and stem. Strengthen your root, so that the judgment that other Masters as less than yours will fade away. In Islam, there is a little known principle called 'Rasala.' It refers to the equality of all prophets. Muslims do not believe that Muhammad is greater than Jesus or Moses. They believe he is the final prophet, not 'better.' There is no 'better' or 'worse' among the saints. It is a sin to create a hierarchy of Masters and to proclaim one above another. Such judgments come from the narrow egotism of the intellect.
Your Master has come to free you, not to addict you to his or her form. The true Master is fierce and will roar at you if you treat the Master like a breast, full of milk. Become weaned after awhile. Don't be a spiritual infant forever. Be free and get on with YOUR life, not his.
Jai Guru Dev!
