How a genuine Tulku will do his beneficial works is up to the Tulku. Relating to the audience or not is our perspective. The Tulku does not need to fit into our perspective on how he relates. The Tulku does not need to fit into our mold, expectations and realities. They operate from a different reality. As the saying goes, what's good for one maybe poison for another.
The Tulku system has produced many great illustrious teachers/examples. The Tulku system is alive and well. The Tulku system is very necessary for the period after Dalai Lama's demise (sorry). It is the great Tulkus within the Gelug School that will stand up with their well known reincarnated names that will speak up for Dorje Shugden.
Any great teacher alive today or recently will attribute their learning, transmissions and teachings to some great Tulku within the masters they have studied under.
Examples:
Zong Rinpoche to Trijang Rinpoche.
Trijang Rinpoche to Pabongka Rinpoche.
Dalai Lama to Trijang and Ling Rinpoches.
The current oracle Tenzin Choepel (Indianapolis, USA) to Zong Rinpoche.
Dagom Rinpoche to Trijang Rinpoche.
Geshe Ngawang Dhargye, Geshe Rabten, Geshe Zopa, Lama Zopa, Lama Yeshe, etc etc all to Trijang Rinpoche.
Pabongka Rinpoche to Dakpo Rinpoche.
Geshe Tendar to Zong Rinpoche.
Lati Rinpoche to Trijang Rinpoche.
Drayab Loden Sherab (Germany) to Trijang Rinpoche.
Gelek Rinpoche to Trijang and Ling Rinpoche.
Geshe Lobsang Tharchin to Trijang Rinpoche.
Gaden Trisur Lungrik Namgyal to Trijang Rinpoche
Denma Gonsa Rinpoche to Trijang Rinpoche.
Domo Geshe Rinpoche to Trijang Rinpoche.
Ling Rinpoche to Pabongka Rinpoche
Geshe Kelsang to Trijang Rinpoche.
The above is just to name a few.
Look at the Great Masters Section of this Website, 90% are Tulkus who have upheld or upholding the Dorje Shugden lineage. Take a look:
http://dorjeshugden.com/wp/?page_id=37Tulkus are indeed important. Are relevant and the system is fine. We need to stop judging, constricting and making rules for how a Tulku must behave according to our very limited methods/ways. After all most of us are just laypeople who find it hard to even hold on to the basic 5 precepts.
