In the process of observing the image of Vajrasattva, start with the face, then proceed to the right hand, the left hand, the right foot, and then the left foot. Alternatively, you can also observe other elements in turn, such as Vajrasattva’s face or bodily ornaments, the whole image in a general sense, or the details of the image, such as the white part of Vajrasattva’s eyes. Having engaged in such careful observation, the image of Vajrasattva will appear in your mind. Some people claim they cannot visualize Vajrasattva clearly, but the fact is that without following the instruction on visualization or devoting time to practice, there is no way one can visualize Vajrasattva clearly. It’s not easy to perform visualization, so you should not give up altogether if the image fails to appear in your mind after only one or two afternoons of observation. To successfully have a clear vision requires persistent practice.
