Is there a Buddhist tradition or practice, which involves developing or showing metta towards a non-sentient entity ... for example, towards a jar of rice?
If not, why not?
Is it theoretically possible (according to Buddhist theory) that such a practice might have an effect, an effect not only on the mind of the practitioner but also on the object ... for example, might speaking kindly to a sealed jar of cooked rice cause it to rot more slowly (as suggested by Masuro Emoto's rice experiment)?
Masuro Emoto's rice experiment was to put cooked rice in three sealed jars: then say hateful words to one jar, loving words to another, and ignore the third. Allegedly the rice jar to which were said loving words does well (rots more slowly), and the ones you ignore and say bad words to will do less well (they rot or grow mouldy more quickly than the other one).
Edit : the experiment didn't work - i also added two slices of the same apple next to the rice - and even the "good" rice and apple got rotten a bit faster
