I was going through my photos from January and realized I don't know what these images and texts mean. The Imperial Palace museum in Taipei has Tibetan artefacts on display. The ol' Chinese Emperors had an interest in Tibetan Buddhism.
3th picture: Namo Buddha Ya, Namo Dharma Ya, Namo Sangha Ya. For the Triratna (Kunchog Sum) I bow down.
4th picture is about: Buddha's very much detailed elaborated great sutra (mDo Phalpo Che: Avatamsaka), first section. The Victorious ten disciples together as for the Bodhisattvas.
