When compared to the other important Tantric system of Vajrayana in Tibet the Muladhara chakra finds no parallel in the same place, unlike the other six chakras. Instead, the Tibetan system positions two chakras on the sexual organ: the jewel wheel in the middle, near the tip, and the tip of the sexual organ itself. These chakras are extremely important for the generation of great bliss, and play an important role in the highest tantric sexual practices. A unique feature, the red drop, called the red bodhicitta, is not located here, but instead at the navel wheel.
