"I have taken hold of the Tibetan tradition of the five buddha families, where each family holds together a color, an element, and above all a psychological disposition, in order to place within it the ecological concerns that run through me, and especially those that bear on biodiversity.
 
With Vajra, blue and of water, I look at anger and aversion, legible in the diverted rivers, the polluted waters, and the retreating glaciers, when the mirror wisdom it holds within would give us back the clarity to see nature as it is rather than as it serves us."
 
— Rentai Caroline Maby
 

 
The five buddha families present a complete image both of the sacred world of awakened mind and of the neurotic world of ego-centered existence.
 
"Vajra is associated with anger, which is transmuted into mirrorlike wisdom. In the cloudiness, possessiveness and aggression of anger, there are qualities of brilliance, lucidity, great energy.
 
Seeing these qualities clearly in the vajra yidam, the essence of anger is spontaneously transmuted into openness and precision. Transmutation is not performed deliberately but automatically follows upon clear insight.
 
Vajra is associated with the element of water. Cloudy, turbulent water symbolizes the defensive and aggressive nature of anger. Clear water suggests the sharp, precise, clear reflectiveness of mirrorlike wisdom. The color white, also associated with vajra, expresses both the all-pervading ice storm of anger and the brilliant reflectiveness of mirrorlike wisdom. Vajra's direction is the east, which is connected with the dispassionate clarity of dawn. The symbol of the vajra family is the vajra (T.: Dorje; Tt.: rdo rje), the thunderbolt scepter which betokens indestructibility and precision."
