From Buddhism's Sacred Scripture: The Sutra of the Lotus of the Wonderful Dharma, Chapter 2, Part 4 of 4

If someone with a confused and distracted mind should take even one flower and offer it to a painted image, in time he would come to see countless Buddhas. Or if a person should bow or perform obeisance, or should merely press his palms together, or even should raise a single hand, or give no more than a slight nod of the head, and if this were done in offering to an image, then in time he would come to see countless Buddhas. And if he himself attains the unsurpassed way and spreads salvation abroad to countless multitudes, he will enter the nirvana of no remainder as a fire dies out when the firewood is exhausted.
