When you invite any Buddha they DEFINITELY COME, even if we cannot perceive them at this time.
Their power to appear is fully ripe and they have great compassion for all those that call upon them even if we are normal people.
Their compassion has no barriers. To believe they are here with you is not pretending but creating the causes to see them in actuality in the future.
Continue your practice and devotion to Tsongkapa for the rest of your days. It is excellent for you and those around you.
