Mind, in Buddhism, refers to our individual mental activity with which we subjectively experience both samsara and enlightenment. The distinctive characteristic of mahamudra meditation is distinguishing and focusing on the conventional and deepest natures of the mind. Discovering and understanding the relationship between mind and reality is essential for achieving both liberation and enlightenment, the goal of mahamudra practice. Because it is difficult to recognize the two natures of the mind, the practice of preliminaries is essential to weaken our mental blocks and build up positive force. To then engage correctly in mahamudra meditation, we need to identify the defining characteristics of mental activity and know how to focus on them in meditation.
