Do plants, animals, and humans have different spirits? ‘Abdu'l-Baha – one of the central figures of the Baha’i Faith – explains these distinctive realms, and what holds them all together. 

“Man is the possessor of a degree of attraction which is conscious and spiritual. Here is an immeasurable advance. In the human kingdom spiritual susceptibilities come into view, love exercises its superlative degree, and this is the cause of human life.”
‘Abdu'l-Baha
