I opine that any altar set up is beautiful because it comes from the heart. May it be a tsa tsa, a printed image, a statue of any size, a thangka, a pendant or even a line drawing. Offerings from the heart are beautiful because from Dorje Shugden's side, He views them as beautiful offerings from the heart. This I learned from my very learned and attained Guru. My very learned and attained Guru also said that once we have gained some realizations from our dharma studies and practices then the altar is in the center of my heart channel.
Thank you, Jacob, for sharing with us picture of your altar, it is lovely.
