Kheer Bhawani, Ksheer Bhawani, Tula Mula shrine or mandir or the Ragnya Devi temple is a Hindu temple situated at a distance of 25 kilometers (16 mi) north-east of Srinagar, Jammu and Kashmir, India, in the village of Tulmul in Ganderbal. It is dedicated to the Hindu goddess Kheer Bhavani constructed over a sacred spring. As is the custom with Hindu deities, the goddess has many names including Ragyna or Rajna, along with variations in honorifics such as Devi, Mata, or Bhagavata. The term kheer refers to a milk and rice pudding that is offered to propitiate the goddess. Kheer Bhawani is sometimes translated as 'Milk Goddess'. The worship of Kheer Bhawani is universal among the Hindus of Kashmir, most of them who worship her as their protective patron deity Kuladevi.
