In Tibetan Buddhism, unique tantric techniques which include visualization (but also mantra recitation, mandalas, and other elements) are considered to be much more effective than non-tantric meditations and they are one of the most popular meditation methods. The methods of "Unsurpassable Yoga Tantra", ("anuttarayogatantra") are in turn seen as the highest and most advanced. Anuttarayoga practice is divided into two stages, the "Generation Stage" and the "Completion Stage." In the Generation Stage, one meditates on emptiness and visualizes oneself as a deity as well as visualizing its mandala. The focus is on developing clear appearance and divine pride (the understanding that oneself and the deity are one). This method is also known as deity yoga ("devata yoga"). There are numerous meditation deities ("yidam") used, each with a mandala, a circular symbolic map used in meditation.
