>Inner Offering (Wylie: Nang chod, Chinese: 内供) is the most symbolic amrita offering assembly, and the Inner Offering Nectar Pill (Wylie: Nang chod bdud rtsi rilbu, Chinese: 内供甘露丸) is a precious and secret medicine of Tibetan Buddhism, which are only used internally for higher ranking monks in Nyingma school. Its ingredients including Five Amrita and Five Meat, which represents five buddha, and five elements respectively. According to Tantras of Chakravarti, and Tantras of Vajravārāhī, a ceremony needs to be held for melting and blessing the Inner Offering Nectar. Five Nectar needs to be arranged in four directions: yellow excrement in the east, green bone marrow in the north, white semen in the west and red blood in the south, blue urine is placed in the center. Four Nectar should come from wise monks and the ova should be collected from the first menstruation of a blessed woman. The Five Meats are arranged similarly, meat of black bull in the southeast, the meat of the blue dog in the southwest, the meat of the white elephant in the northwest, the meat of the green horse in the northeast, and the meat of a red human corpse in the center. After the ceremony, these ingredients will transform into a one taste (ekarasa) elixir, which bestows bliss, vitality, immortality and wisdom. Actual modern practitioner will take a 'synthesized essence' of the Nectar Pill and combined it with black tea or alcohol, but mostly the "Nectar Pill" are derived from plants.[9]
