Right Mindfulness
Ordinarily our minds are full of a whole army of distractions and discursive thoughts. Right mindfulness is being free from these mental afflictions so that there's just one, thing remaining in the mind, and that is the path of practice. One approach to mindfulness practice is to contemplate the six objects of mindfulness: the Buddha, the Dharma, the Sangha, the Precepts, the merits of renouncing worldliness, and the merits of good deeds. The six mindful practices are really the prerequisites to engaging in the four foundations of mindfulness of body, of sensation, of mind, and of dharmas (external and mental objects).
It is not necessary to practice all six mindful Practices before practicing the four foundations. You can choose any one of the six as a preparatory practice. Once we engage in the four foundations of mindfulness, we can enter the eighth noble path of right concentration.
