Ishana, is a Hindu god and the dikapala of the northeast direction. He is often considered to be one of the forms of the god Shiva, and is also often counted among the eleven Rudras. He is venerated in Hinduism, some schools of Buddhism and Jainism. In the Vastu Shastra, the north-eastern corner of a plot of land is referred to as "Ishana". Ishana also shares qualities with Samhara Bhairava and is therefore a part of the Ashta Bhairava.
