According to Pabhongka Rinpoche in Liberation in the Palm of Your Hand, unless we do the offerings ourselves we will not accumulate any merits. An excerpt from the book says as follows:-
" You must put the offerings out yourself. If you make your pupils or your servant arrange the offerings, you will not receive any merits"
This is from the point of view of the person engaging someone else to do the offering on his/her behalf.
For the person engaged to do the offerings, I would imagine that with the rights motivation coupled with the physical actions in the process of making offering, merits would definitely be accumulated. The extent of merit would depend on the quality of the person's motivation, the lowest would be to obtain things for this life to the highest Bodhicitta motivation, the thought of attaining enlightenment for the sake of all sentient beings,
Thanks for sharing this, WT.
I can see the logic of this statement.
As with Karma and everything else in Buddhism, it is about empowering the self or the individual to do something for themselves - even to change their destiny so-to-speak.
I guess, when we seriously think about it, if we truly want to gain merits, we should do the acts itself that will grant us the merits.
In the same vein, if we want to purify our karma, we have to do the acts, prayers and pujas to purify and not someone else doing it for us.
I believe our motivation to do anything sets the stage, and our dedication after the act seals the deed.
