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.
“Sentient beings, self and others, enemies and dear ones—all are made by thoughts. It is like seeing a rope and mistaking it for a snake. When we think that the rope is a snake, we are scared, but once we see that we are looking at a rope, our fear dissipates. We have been deluded by our thoughts. Likewise, mentally fabricating self and others, we generate attachment and aversion.” ~Dilgo Khyentse Rinpoche
