There is the concept of dedication of merit to the deceased, but it is debatable whether these are actually "received" by anyone, or whether it's simply a better, more productive way to respond to death than to wallow and grieve.
Strictly speaking, the deceased are not appropriate subjects of metta. I remember Ben speaking about this recently... and hopefully he can point us in the direction of an appropriate resource.
And finally, something for you...Snp 3.8 - Salla Sutta: The Arrow http://www.accesstoinsight.org/tipitaka ... .irel.html
All the best.
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
