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.
"Despite the fact that we are a ceaselessly transforming stream, interdependent with other beings and the whole world, we imagine that there exists in us an unchanging entity that characterizes us and that we must protect and please. A thorough analysis of this reveals that it is only a fictitious mental construct".
Shechen Rabjam Rinpoche.
