This is really a good question to contemplate for those who follow HH Dalai Lama and those who confused or in dilemma when come to respect HHDL and want to be loyal to their guru and lineage at the same time.
Samaya with one's guru will be equally importance or if really want to measure in quantity, the "value" would be no difference, whether your guru is with big name or not.
Validity of an investigation, opinion and view on certain practice such as Dorje Shugden is "legal", or whether He is an enlightened being or not, is not depend on who is the person speaking, but should be how strong the evidence and proof the person has presented, to make you believe in.
The issue of Dorje Shugden - including He is a spirit or enlightened being/His practice will threaten HHDL's life and the stability of Tibet and etc - not only brought out the issue of religious freedom, but for me, it is a test for a practitioner's wisdom on following blindly or with wisdom well...Did we criticize one's practice/a guru by blindly follow an instruction by a person on high throne & with big name, without enough investigation from our side?
Did we listen or read enough to understand both sides' stories before making a stand or worst verbally or physically attack another person's belief? Or we just follow the mainstream opinion to be safe? Did we want to be safe, not being left out or avoid being attacked by the majority, so just follow whatever majority are doing - even the action is violence, violating basic human rights, harmful and hurting another group of people?
This question apply to practitioners and anyone. And it applies not only on the issue of Dorje Shugden, but can be extended to issue of everyday life - including political, economic and etc.
