Once a travelling Lama told me that whenever we have the fortune to own/be near the presence of a Lama Tsongkhapa statue, it is likely either our secular lives will flourish and we will have the conditions to meet with Je Lama's teachings in the future. This is a testament that Lama Tsongkhapa's teachings not only provides us on a material level because His practice such as the Gaden Lhagya-ma has encompasses all sorts of teachings such as wealth deity practices and this will ensure not only our material wealth but also that of our spiritual growth and attainments.
Monasteries such as Sera as shared by Namdrol here is another living testament on two levels; Lama Tsongkhapa's teachings ensures that we are taken cared for both spiritually and secularly and on a higher level, where there is truth (ie: Dharma) it will not die down no matter how much suppression both physical and mental is laid upon them. It will only grow grow GROW!
Likewise, with the current ban on Dorje Shugden, there is only ONE WAY to get out of the situation which is to show what the TRUTH behind Dorje Shugden ban is and to continue to educate and create awareness to the people from around the world and one day if not soon, the ban will be lifted!
I wish for that day to come soooooooooooon!
