The story above portrays the importance of a healthy Guru-disciple relationship. When the Guru passes on, disciples take on the responsibility to spread the Dharma teachings and ensure the pure lineage is preserved. When we talk about Guru devotion, we have to sacrifice, submit and do things for our Guru that we normally would not do, then from there, we surrender to our egos and bad habituation, we collect merits. We do not overdependent on others on our spiritual path. Maintaining the positive energy and motivation in our spiritual path often seem like a challenge because our understanding of Dharma and the working of Karma is not deep enough.
The Connections Sutra clearly indicated this fact: " Buddhas connote wash away others' negative potentials, nor remove their suffering like one would pull out a thorn from a foot. They cannot transfer their realizations to anyone. They can only indicate they way by teaching about reality."
The strong guru devotion must have deep-rooted in Trichen Lama that his current work is continuously benefiting others in many ways, as a heart disciple of great Geshe Yeshe Wangchuk, the fearless Lobsang Drakpa's lineage holder.
