From a doctor you get a prescription. From two doctors you get consultation. From three doctors you get your own cremation.
Even so, if you have many Gurus you will be bewildered. You will be at a loss to know what to do. One Guru will tell you: “Do Soham Japa”. Another will tell you “Do Japa of Sri Ram.” A third Guru will tell you “Hear Anahata Sounds”. You will be puzzled. Stick to one Guru and follow his instructions.
The traditional Christian emphasis upon the unique salvificity of Jesus (Jesus as the embodied root Guru of the Christian) can thus be more fully understood as a necessary part of spiritual sadhana, a part accepted by serious practitioners of all lineages and traditions. The traditional Christian emphasis reflects the divine physics of Enlightenment. All Yogas begin and end in Guru-Bhakti Yoga. Without Guru-Bhakti Yoga, there is no true religion. Swami Sivananda refers specifically to the embodied root Guru, below, but such statements can also be applied to the non-bodily bound Heart-Beloved:
52. A Guru is necessary for every aspirant in the spiritual path.
53. It is only a Guru who will be able to unveil the mystery and meaning of real life and show the way to God-realisation.
54. It is only a preceptor who can teach the disciple the secret about Sadhana.
55. An ideal Guru is one who has attained God-realisation.
56. Such a Guru is pure in thought, word and deed.
57. He has mastery over the senses and the mind.
58. He has knowledge of all the scriptures and is simple, kind and truthful.
59. Guru will be able to awaken the hidden divine power in the innermost core of disciple’s heart.
60. If a disciple has done good Karma in his previous births, if he is doing them now, and if he is sincere and longing for God, he will be sure to meet the real Guru.
61. To derive the full benefit from the Guru, disciple must have implicit faith in him and true devotion for him.
62. The disciple will achieve results in proportion to his faith in his Guru.
63. It is the spiritual teacher who will show the way and finally lead one to God.
64. Guru is none but God Himself in human form.
