When one has done the first six limbs of the seven-part practice, one has already accumulated some merit. In addition, there are also merits or good karma one has accumulated through other actions such as charity, meditation or even just making others smile. One has accrued a lot of good deeds and these must be secured in the mindstream. In order to make a positive and lasting imprint on one’s mind, one must carry out a dedication of these merits or good deeds.
If one does not dedicate the merits, Buddhist texts state that a moment of anger or regret can fully erase them. It is like a monetary saving, which can be lost to thieves or robbers if not secured properly through methods such as fixed deposit or investment. Thus, any meritorious deed must be promptly secured through dedication. Besides, dedication also helps the merits to grow perennially, just as financial savings grow with interest.
