Mindfulness and Perception
Achieving equanimity in the face of unpleasant sensations can transform how we perceive anxiety and other negative emotions. By training attention to focus on the raw qualities of experience, one can shift from a dualistic mindset to a deeper understanding that the self is not separate from sensations. This practice not only enhances mindfulness but also reveals the illusory nature of the self, leading to profound insights about awareness and perception.In this clip

Can one experience both positive and negative feelings simultaneously in the beginning?
