Manipura is considered the centre of dynamism, energy, willpower and achievement (Itcha shakti.), which radiates prana throughout the entire human body. It is associated with the power of fire, and digestion. It is also associated with the sense of sight, and the action of movement. Manipura is "the center of etheric-psychic intuition: a vague or non-specific, sensual sense of knowing; a vague sense of size, shape, and intent of being."As such, some psychics recommend "listening" to it since it may help in making better decisions in one's life on many different levels.
