Ajna is described as a transparent lotus flower with two white petals that represent the nadis (psychic channels) Ida and Pingala, which meet the central Sushumna nadi before rising to the crown chakra, Sahasrara. The letter "ham" (हं) is written in white on the left petal and represents Shiva, while the letter "ksham" (क्षं) is written in white on the right petal and represents Shakti.
MEDITATION:
Six chakra is clear, there are enhanced intellectual and psychic abilities. Memory is good and perceptions are accurate. Sinuses are clear, hearing and vision is broadened by ability to use inner senses to amplify the information gained by the five physical senses. Through ability to consciously travel into the higher dimensions of inner reality, ability to visualize is amplified, imagination is expanded, and is able to project visions and ideas into the outer world.
