Key Terms to Review (22)
Advaita Vedanta: Advaita Vedanta is a non-dualistic school of Indian philosophy that teaches the fundamental oneness of Brahman (the ultimate reality) and Atman (the individual self). It emphasizes that the apparent distinctions between the self and the universe are illusory, leading to a deep understanding of the nature of existence and liberation from the cycle of birth and death.
Aham brahmasmi: Aham brahmasmi is a Sanskrit phrase that translates to 'I am Brahman,' expressing the fundamental identity between the individual self (Atman) and the ultimate reality (Brahman). This concept is central to Advaita Vedanta, highlighting the non-dualistic nature of existence where the realization of this unity leads to liberation from the cycle of birth and death.
Atman: Atman refers to the true self or soul in Indian philosophy, considered the essence of individual identity and consciousness. It is central to various philosophical discussions and practices, often understood as the eternal and unchanging aspect of a person that transcends physical existence and connects with the ultimate reality.
Avidya: Avidya refers to ignorance or lack of knowledge, particularly in the spiritual sense, which is seen as the root cause of suffering and the cycle of birth and rebirth. This concept plays a critical role in various philosophical schools, emphasizing how ignorance clouds perception of reality and prevents individuals from realizing their true nature.
Brahman: Brahman is the ultimate reality and cosmic principle in Hindu philosophy, often described as the source of all existence, consciousness, and bliss. This concept connects to various philosophical discussions surrounding the nature of the universe, the self, and the relationship between the individual and the infinite.
Dharma: Dharma is a key concept in Indian philosophy that refers to the moral, ethical, and righteous duties or responsibilities one must follow in life. It encompasses an individual's obligations to themselves, their family, society, and the universe, often varying based on one's age, caste, and life situation. This concept is foundational to various Indian philosophical traditions and influences how individuals navigate their lives and spiritual paths.
Jagrat: Jagrat refers to the waking state of consciousness in Indian philosophy, particularly within the context of the Upanishads. This state is characterized by the perception of external reality through the senses and is essential for understanding the different levels of consciousness that are central to the Upanishadic teachings. The experience of jagrat serves as a foundation for exploring higher states like svapna (dream state) and sushupti (deep sleep), emphasizing the importance of self-awareness and the nature of reality in Indian philosophical thought.
Karma: Karma refers to the law of cause and effect in which an individual's actions (both good and bad) influence their future circumstances and experiences, particularly in the context of reincarnation. This concept connects deeply with ideas of moral responsibility and ethical living across various Indian philosophical traditions.
Mahavakyas: Mahavakyas are key philosophical statements found in the Upanishads that express the essence of non-dualism and the relationship between the individual self (Atman) and the ultimate reality (Brahman). These profound sayings serve as a foundational aspect of Advaita Vedanta, particularly in understanding the teachings of prominent philosophers like Adi Shankara, who emphasized their significance in realizing one's true nature and unity with Brahman.
Maya: Maya refers to the concept of illusion or the deceptive nature of the material world in Indian philosophy, particularly within Vedanta. It suggests that the world we perceive is not the ultimate reality but rather a veil that obscures the true nature of existence, leading to misidentification with the physical realm instead of recognizing the underlying spiritual truth.
Moksha: Moksha refers to the liberation or release from the cycle of birth, death, and rebirth (samsara) in Indian philosophy. It signifies the ultimate goal of human existence, where the individual soul (atman) is united with the absolute reality (Brahman) or attains a state of eternal bliss and knowledge.
Non-dualism: Non-dualism is a philosophical concept that posits the fundamental oneness of reality, asserting that there is no separation between the individual self (Atman) and the universal essence (Brahman). This idea challenges dualistic thinking by emphasizing that perceived distinctions are ultimately illusory, leading to a realization of unity in diversity.

Purusha: Purusha is a key concept in Indian philosophy representing the cosmic spirit or the universal self, often seen as the observer and the source of consciousness.

Purusha also highlights significant philosophical distinctions within various schools, impacting understanding in areas like epistemology and psychology.

This ongoing process is often seen as a state of suffering and entrapment from which individuals seek liberation, highlighting the transient nature of existence and the continual quest for spiritual awakening.
Sushupti: Sushupti refers to the state of deep sleep or unconsciousness in Indian philosophy, particularly within the context of the Upanishads. It is one of the three states of consciousness—waking (jagrat), dreaming (svapna), and deep sleep (sushupti)—and represents a condition where the individual experiences a lack of duality and a sense of unity with the ultimate reality. This state is significant for understanding the nature of existence and consciousness, as it reveals insights into the self's relationship with Brahman, the ultimate reality in Hindu philosophy.

This state is essential in understanding consciousness and is deeply linked to various Indian philosophical concepts and practices.
Upanishads: The Upanishads are ancient Indian texts that form the philosophical basis of Hinduism, exploring the nature of reality, the self (Atman), and the ultimate reality (Brahman).
