Shabkar critique of Sectarianism within Buddhists

~ One of Shabkar’s most critical indictments of sectarianism in his autobiography occurs in a song sung while on retreat on Mahādeva Island in Lake Kokonor. The song suggests that Tibetan Buddhists have fallen from a golden age when all the Buddha’s teachings were 
once understood as non-contradictory. In this fallen age, Buddhists are engaged in sectarian bias and rivalry: 

Due to the kindness of holy forefathers of the past,
In the snow ranges [of Tibet]
Many profound Dharma teachings spread.
However, Dharma practitioners, 
Having grasped [the teachings] as contradictory – like hot and cold, 
Engage in sectarianism – attachment and aversion.
Some of the Holy Ones have said
That Madhyamaka, Dzokchen and Mahāmudrā
Are like sugar, molasses, and honey –Each being as good as the other.
Thus, I have listened to and contemplated
On all the teachings without sectarian bias.
Sectarian practitioners with attachment and aversion
Please do not scold me. 
When the sunlight of pure perception
Spreads on the lofty white snow mountains
[That are] Madhyamaka, Dzokchen and Mahāmudrā,
It is certain that a river of blessings will arise.!
