No, Mindfulness and Awareness are not the same, they carry different concepts, mechanisms, and senses in the field of meditation. The term mindfulness is used by Gautam Buddha as Samyak Smriti (Right Mindfulness) for noticing the activities of the body, mind, and heart in a relaxed, non-judgemental way for meditation. Mindfulness holds both the subjective and objective aspects of knowing or noticing but the state of Awareness is completely free from the subjective and objective phenomenon and holds a pure state of knowing or noticing. Mindfulness is a method or a technique toward Awareness. The practice of mindfulness leads the practitioner to experience a state of Awareness.
