In plain words
Giving shelter to all people without distinction of caste, the trees proclaim equality to all; "It is not right for us to crave so much for the body," say the mountains, as they bear cold, sun and rain; "Do not fret over tomorrow and the evening after," the birds teach the lesson of contentment; "The body is not eternal, worldly life is an illusion," say those who leave the body and depart; "The delusion of 'mine' and 'I' is unworthy," proclaims the shower of tears that Mother Nature weeps. For every creature that lives, Nature is the school; look well: is not the true Guru Sāī, Śrī Hari?
Embodiments of Prema!
To the one who poured water and raised them and to the one who harmed them alike, the trees give cool shade and sweet fruit, and so they teach equality. Though such teachings have been going on for humanity from time without beginning, man has still not opened his eyes. People do not understand the principle of this Nature, which casts off the differences of one's own kind, another kind and one's own creed, holds to humanity with equal regard, and teaches divinity. When the trees themselves teach such great lessons, why can man not recognise his humanity? This is what we must think about today. For every human being the trees themselves are the first Guru.
"It is not right for us to crave so much for the body," say the mountains, as they bear cold, sun and rain.
Man nourishes the principle of the body with all kinds of attachment and possessiveness, becomes bound to it and a slave to it, and simply forgets his own divinity. Through this very attachment and possessiveness man takes this worthless body as his support in many ways, forgets the divine Nature which that support holds, and sinks into selfishness.
All religions teach us to hold pleasure and pain in equal balance and to lead a holy life.
