In terms of the first aspect of practice “cultivation concerning the characteristics of dharmas,” by contemplating the nature of breath lacking substantial Being, one proceeds to contemplate the nature of body, which is what one’s breath is dependent upon. By conceiving emptiness of body, which is composed of four elements (earth, water, fire, and wind), one continues to contemplate mind, which is what one’s body relies on. One sees that the mind is also empty, for it is created by the combination of conditions. In terms of the second aspect of practice “cultivation concerning realization of truth,” it is to “internally realize emptiness as the Absolute Truth.” “Gradually, [one] is able to penetrate and understand the distinctiveness of one’s body-form and breath. [One] also knows that one’s body corresponds with the mundane astronomy and geography and can embrace samäclhis within the three realms.” (Vol. 2, Page 180)
