Upeksha is the fourth of the Buddhist Brahmaviravas ("four immeasurables"), which are also mentioned in Patanjali's Yoga Sutras. It is a state of mind taught both in Buddhism and in yoga. Although it is sometimes translated as indifference, the correct translation is equanimity. Upeksha means leading a balanced life, removing intolerance and caring for all equally.
Upeksha teaches the practice of non-attachment, an important element in yoga practice both on and off the mat.
