The Bhikshuka Upanishad also known as Bhikshukopanishad, is one of the minor Upanishads.The Bhikshuka Upanishad is a minor Upanishad attached to the Shukla Yajurveda. It is classified as one of the Sannyasa (renunciation) Upanishads. The Upanishad describes four kinds of sannyasins (Hindu monks), their eating habits and lifestyle. Yoga is the path of spiritual liberation for all four. Of these, the Paramahamsa monks are discussed in this text at greater length, and described as loners who are patient with everyone, free from dualism in their thoughts, and who meditate on their soul and the Brahman. Bhikshuka means "mendicant" or "monk", and is derived from the root word Bhiksu meaning "one who subsists entirely on alms".
