Dahlia

The Vṛndāvana forest was as sanctified as the clear mind of a devotee and was full of bees, flowers and fruits. There were chirping birds and clear-water lakes, with waters that could relieve one of all fatigue. Sweet-smelling breezes blew always, refreshing the mind and body. Kṛṣṇa, with His friends and Balarāma, entered the forest and, seeing the favorable situation, desired to enjoy the atmosphere to the fullest extent. Kṛṣṇa saw all the trees, overloaded with fruits and fresh twigs, bending down to touch the ground as if welcoming Him by touching His lotus feet. He was very much pleased by the behavior of the trees, fruits and flowers, and He began to smile, realizing their desires.
(Krsna Book 15)

Just like one flower picked up from a plant offered to Kṛṣṇa is offering benefit to that plant. Because his energy is in the service of Kṛṣṇa. Similarly, the person who has manufactured this machine, when it is employed in Kṛṣṇa consciousness business, he’s benefited.
