Why is there a need to cultivate the “Root Guru Practice”?

All Tantrayana accomplishments are derived from the blessings of the Root Guru, as all pith instructions are transmitted from the Root Guru. This kind of transmission not only represents the affinity of all lineages, but it also represents the affinity of realizing the state of emptiness taught in Mahayana teachings. Therefore, cultivators must cultivate the Root Guru Practice without fail. Furthermore, the Root Guru Practice is the shortest and swiftest route for disciples to achieve a spiritual response with the Root Guru. Hence, as long as one is a True Buddha disciple, they must commit to cultivating the Root Guru Practice until they achieve genuine results. Only then can they proceed to cultivate the Personal Deity Practice. In this way, they avoid deviating from the path and all pitfalls.
