The Heart, and the Unconditioned Dharma. The eight consciousnesses are included in the Dharma of the Heart. In the Mahayana Hundred Dharmas, the discussion of mindfulness is placed first to show the importance of these dharmas.

In the loka of the Order of the Eight Consciousnesses, the characteristics and functions of the eight consciousnesses are further described in detail. Since in the description there are many terms related to the corresponding dharmas and which are not compatible with consciousness, it is first necessary to understand the Mahayana Hundred Dharmas, where the related dharmas are explained.

Even if one does not intend to study the doctrine of Yogācāra in depth, yet by studying matters related to consciousness, one can distinguish what is real from what is not. He can understand that it is consciousness that gives rise to distinctions, and does not mistake them for bright minds that are originally clear and pure. Thus he can quickly leave consciousness and dwell in the true mind.

All dharmas are brought about by alaya consciousness. With the understanding that alaya consciousness arises as a result of momentary ignorance of the true nature of mind, it is a combination of pure mind and illusion. So as long as we know that all the dharmas it gives rise to are unreal, and if we don't cling to ego and phenomena, the consequence is that we can practice to return to the pure true nature of the mind. Then after eliminating ignorance, we can become perfect Buddhas.
