by Zhaxi Zhuoma Rinpoche is from the book H.H. Dorje Chang Buddha III:
In Tibetan esoteric dharma, there are lineages of the Great Precious Pill, the Supreme Precious Pill, the Nectar Pill, the Vajra Pill and the Long Life Pill. Rinpoches, in general, have these five precious pills. But most of them are of the ordinary type, not the holy precious type. Holy precious pills and ordinary ones are totally two different concepts. I personally saw holy Nectar Pills bestowed by Buddha. I also personally saw true Vajra Pills. Such pills exist in the ordinary type and holy type. Ordinary precious pills (rinchen rilbu) used in Tibetan medicine undergo complex processing methods and can contain over one hundred ingredients including gold, silver, copper, iron, mercury, coral, pearls, lapis lazuli, sapphire, emerald, turquoise and ruby in their detoxified form as well as special herbs and other ingredients. They depend on the blessing and spiritual powers of the physicians and rinpoches who prepare them. However, they are still of a worldly nature and not the same as holy precious pills.
I follow my Great Dharma King Buddha Master Wan Ko Yeshe Norbu and am by His Holiness’s side constantly. Therefore, I have experienced many magnificent and real manifestations of Buddha-dharma. Now I am going to tell everyone about the experience of the true Vajra Pill. When the vajra holy mantra and mudra are practiced, the Vajra Pill will jump, even transform into rainbow light and soar into the sky. I vow that the events reported here are true and happened as reported. If not, I am willing to bear the karmic retribution of the hell realms.
All of the this happened in April, 2003.
I traveled from San Francisco to Los Angeles to see H.H. Great Dharma King Wan Ko Yeshe Norbuu. During the trip I suddenly saw a colorful and large rainbow light appear in the sky. The rainbow completely surrounded the sun. There were also Sanskrit symbols in the sky. Just as the rainbow was fading from sight, I was able to take a picture of the bottom half of this light by focusing the camera below the sun. You can see how large this circular rainbow was from the size of the tiny parking lot light-poles shown in the lower left hand side of the photo. A dignified Buddha–Dorje Chang Buddha–appeared in the middle of the rainbow. Then the Buddha became H.H. Master Wan Ko Yeshe Norbu, who was wearing a red robe and was sitting in the middle of the rainbow. It was awesome and extremely wonderful.
I was fortunate to receive a true Vajra Pill from a great holy one. It was in my hand, not in H.H. Great Dharma King Wan Ko Yeshe Norbu’s hand. When His Holiness performed the empowerment initiation, the Vajra Pill jumped in my hand just as if it were alive. It not only jumped but, in sync with the sound of the empowerment mantra recited by H.H. Great Dharma King Wan Ko Yeshe Norbu, it started to circle around and left my hand. It transformed into dazzling bright red lights and soared into the sky. At that time, I saw that H.H. Great Dharma King, who sat far away on the dais, had become a blue Vajradhara. The blue light was shining bright. The scene was very dignified. This is when I first saw the true holy Vajra Pill and the true identity of my Master. At other times and other mandalas, I have been fortunate to see the vajra pill again. One time I heard it dance and another time I heard it chant mantras. Today I tell everyone these personal experience in a concise way. My Dharma King Buddha Master Wan Ko Yeshe Norbu is the supreme and highest holy being. May all living beings have the good fortune to hear, learn, and practice the true Buddha-dharma and quickly attain enlightenment.
