The nature of reality is devoid of the extreme notions of existence and nonexistence, so it corresponds to the madhyamaka view. Reality cannot be fully expressed in language, so it is in keeping with the teachings of prajnaparamita. Everything is perfect within its own natural condition within the realm of reality, both in terms of samsara and nirvana, so it is in keeping with the views of dzogchen. In reality, nothing is intrinsically evil or intrinsically good, so it is in keeping with the views of the mahamudra teachings. To understand that reality is all pervading and that there is no need to abandon defilements because they can be used to enhance your spiritual practice is in keeping with the teachings of tantra.
