The following is recited at yizkor:^[1] Passages taken from the yom tov yizkor liturgy  

May God remember the soul of my father, (Ploni ben Ploni), who has gone on to the other world. Remember him today, and for that purpose I donate to tsedaqah^[2] Tsedaqah (along with teshuvah and tefilah) to avert harsh decrees. Cf. Bereishit Rabbah 44:15   for his sake, so that his soul may rest in Gan Eydn with the souls of Avraham, Yitsḥaq, Yaaqov, Sarah, Raḥel, and Leah and with the souls of the other righteous men and women who are in Gan Eydn, and let us say amen.

May God remember the soul of my mother, (plones bas plones), who has gone on to the other world. Remember her today, and for that purpose I donate to tsedoke for her sake, that her soul may rest in gan eydn with the souls of Avraham, Yitsḥaq, Yaaqov, Sarah, Rivqah, Raḥel, and Leah and with the souls of the other righteous men and women who are in Gan Eydn and let us say amen.

May God remember the souls of my father and mother, my grandfathers and grandmothers, my uncles and aunts, my father-in-law and my mother-in-law, my brothers and sisters, who have gone on to the other world. Remember them today, and for that purpose I donate to tsedoke for their sake so that their souls may rest in Gan Eydn with the souls of Avraham, Yitsḥaq, Yaaqov, Sarah, Raḥel, and Leah and with the souls of the other righteous men and women who are in Gan Eydn, and let us say amen.

May God remember the soul of (Ploni ben Ploni) and the souls of all of my friends and relatives from my father’s side and from my mother’s side, those who have died as well as those who were martyred for your Holy Name’s sake, by drowning or by strangulation. Remember them today, and may my donations to tsedoke memorialize their names. For this deed, may their souls rest in Gan Eydn with the souls of Avraham, Yitsḥaq, Yaaqov, Sarah, Rivqah, Raḥel, and Leah and with the souls of the other righteous men and women who are in Gan Eydn and let us say amen.

On holidays, this is said:

May the One who blessed our ancestors^[3] From the mi sheberakh given for the honor of an aliyah at a Torah reading.   Avraham, Yitsḥaq, and Yaaqov, bless (Ploni ben Ploni), who has vowed to give tsedoke to memorialize the pure souls of those we have caused to be remembered today. For the sake of the blessed Holy One and for the sake of their holy Torah and for the sake of the holiness of this day, may the blessed Holy One guard and protect him from sickness and bestow blessings upon him and grant him success in all of his endeavors, upon him and upon all Yisro’el, for all are brothers, and let us say amen.

On Yom Kippur, this is said:

May the One who blessed our ancestors Avraham, Yitsḥaq, and Yaaqov, bless (Ploni ben Ploni), who has vowed to give tsedaqah for the sake of the pure souls of those we have caused to be remembered today before the blessed Holy One and for the sake of their holy Torah and for the sake of the holiness of this day. Therefore may the blessed Holy One protect him and guard him from all pain and from those who would cause him suffer and from all illness. Inscribe (Ploni ben Ploni) in the Book of Life and grant him a good life on this Day of Judgment. Bestow blessings upon him and success in all his endeavors, and upon all Yisro’el, for all are brothers, and let us say amen.

Compassionate Father^[4] A paraphrase of the prayer, Av Harokhomim   who resides in the heavens above, may you in your great mercy, remember the good and pious and righteous people and the holy congregations who were martyred for the sanctification of the Name. They were lovely and beloved in their lifetimes and they went to their deaths together. They were swifter than eagles and mightier than lions^[5] 2 Samuel 1:23   in their attempts to do with lovingkindness the will of their Creator and to please Hashem. May God remember them for good, together with all other righteous people of the world, as it is written in the Torah of Mosheh, the man of God: “Nations, praise ye his nation.”^[6] Deuteronomy 32:43   And through Your servants, the prophets, for it is written: “God rests in Tsiyon.”^[7] Joel 4:21  

This tkhine should be recited after the yizkor service:

May it be your will, God, my God, and God of my ancestors, thatyou may act graciously towards the holy souls who sigh and praise you and pray for your holy people. Include among them the souls of my relatives, both from my father’s side and from my mother’s side, and all the souls that stand in the three rows in Gan Eydn and all those who praise God, our King, and pray for life and happiness. With all my strength, I pray to you for your mercy.

May your ears accept my plea with mercy. May you turn away in confusion all wrath and destruction directed at your people and may you grant life and peace and good livelihood – indeed, wealth and honor and length of days and years to me, my husband, and my children. May you give us a good heart that we may serve you with complete fulfillment. And may your grace reach all the holy souls and the souls of my father and mother so that they may arise and come before your holy merciful throne, and may their resting place be there. May you bind up the souls of my father and mother – and all holy souls – in the innermost sanctuary of the palace which no eye can comprehend, except for yours. May you make purity shine upon their souls, and may you satisfy them with the bounty of your house, and may you let them drink from the river of Gan Eydn.^[8] See 1 Enoch (Ethiopic, Slavonic) and Pereq Gan Eden: Under the Tree of Life flow four rivers, one of milk, the other of balsam (alternately oil or water), the third of wine, and the fourth of honey. See Louis Ginzberg, Legends of the Jews vol. 1, “The Ten Generations” p.132 (with note in vol. 5, p. 159) and “The Creation of the World” p.20 (with note in vol. 5, p.29): “These four streams are frequently mentioned in the legends; comp. 2 Enoch 8:5; PR 38, 163a; Aggadat Shir 4, 83-84; see also vol. I, p. 132; vol. II, p. 315; Visio Pauli 23; Koran 47. 16-17. While in the Koran the stream of oil is replaced by a stream of fresh water, it is just this stream of balsam which is frequently alluded to in rabbinic literature; BR 62 (beginning); Ta’anit 25a; Yerushalmi ‘Abodah Zarah 3, 42c; Tan. B. II, 131; Bacher, Agada der palastinensischen Amoraer, II, 102, note 7; Jeremias, Babylonisches im NT, 47. On the wine preserved for the pious, comp, Sanhedrin 99a and Matthew 26:29; Targum Eccl. 9:7, where the Midrash given in the text was very likely made use of.”  

I beseech you, dear God, shed your light upon the souls of relatives and upon all the people who live on the earth. May the Shekhinah^[9] Cf. Ezekiel 43:2   shine forth, and may you tell the angel who is appointed over them to lighten their sentence, and may they find their resting place and be at peace, and may they rise continually from one level of heaven to another under the wings of the keruvim.^[10] Cf. Isaiah 6:1-3   Amen, may it be your will.
