This teaching has since been passed down through an unbroken lineage of masters to the present day. During the time of Muchen Sempa Chenpo Konchok Gyaltsen, Lamdre was divided into two sub-traditions: The Explanation for Private Disciples or the uncommon Lamdre (Lobshey) and the Explanation for the Assembly or the common Lamdre (Tsokshey).
The crux to this golden teaching is the inseparability of the worldly existence (Samsara) and enlightenment (Nirvana). It follows that Nirvana is merely a transformation of Samsara. There is no abandoning of Samsara in order to achieve Nirvana, as the mind is the root of Samsara and Nirvana. Realising this inseparability is the key to attaining enlightenment.
It is said that Lamdre is the complete path to enlightenment, and is divided into two parts: the preliminary section and the tantric section. The preliminary section contains the instructions and teachings on sutras of Lord Buddha and focuses on the three visions: impure vision, the vision of experience and the pure vision. The tantric section is esoteric or tantric teachings, which include teachings on the Three Tantras. Lamdre is given by a single teacher (who is an officially recognised lineage holder) in a single place over a period of four to six weeks generally. Within the Sakya school, wherein the Lamdre lineage lies, there are only a handful of lineage holders in any generation
