Can't the whole Buddha be sacrificed casually? Is it different from person to person? I heard that some people can't worship the whole Buddha well, right? Please advise.

Sacrificing a statue is not much different from many statues. As long as you are sincere, giving or not giving is just a form. As long as you practice correctly and have an upright heart, you will accumulate wealth, but if you don't have compassion and compassion for all beings at the same time, unjust relatives and creditors will interfere with your practice because of karma, so it is called making up for it. All your achievements will be rewarded, and all living beings will benefit, so there will be no obstacles.
