Mindfulness is integral to yoga and involves being fully present in each moment. The speaker emphasizes that mindfulness means the mind is focused on the task at hand, contrasting it with the distracted nature of human thought, which often wanders due to various unmet needs. Unlike animals, who focus solely on immediate survival needs, humans have complex desires leading to a divided mind. This scattered attention can cause suffering, prompting individuals to seek change. Mindfulness teaches awareness, encouraging individuals to be conscious of their actions, whether simple tasks like brushing teeth or engaging in conversation. The goal is to cultivate a habit of presence in everything one does, fostering deeper alertness and intentionality in daily activities.
