Musar על סוכה 98:8

And, in truth, how great is this mitzvah in the eyes of the Blessed L-rd, it being written (Michah 6:8): "He has told you, O man, what is good, and what the L-rd requires of you — but to do justice and to love chesed, etc." And Chazal have said (Succah 49b): "'to do justice' — this is din; 'and to love chesed' — this is gemiluth chasadim." And he also fulfills in this the mitzvah of (Devarim 29:9): "And you shall walk in His ways," as we find in Sifrei on the verse (Ibid. 10:12): "'to walk in all His ways' — these are the ways of the Holy One Blessed be He, as it is written (Shemoth 34:6): 'Hashem, Hashem, the G-d who is merciful and gracious, slow to anger, and abundant in chesed, etc.'" And Chazal say (Bava Metzia 30b): "R. Yosef taught (Shemoth 18:20): 'And you shall apprise them of the way' — this is gemiluth chasadim."

It is also good to cause bridegroom and bride to rejoice, as it is said, "The voice of mirth and the voice of gladness, the voice of the bridegroom and the voice of the bride" (Jer. 7:34), but one must be very careful not to amuse them with vulgar speech or jests for this type of rejoicing brings Divine Wrath. Nor should men and women mingle in the precept of causing bridegroom and bride to rejoice, for this is too frivlous. And even in mourning and during the Eulogy, the Sages said : "Let the men sit by themselves and the women by themselves! All the more is this true in rejoicings and we have learned 'Only to do justly, and to love mercy, and to walk humbly with thy God' (Micah 6:8), and "walking modestly" means — the funeral procession and bringing the bride under the Wedding Canopy" (Sukkah 49b).

Especially should he be generous with his knowledge of the Torah, teaching every man knowledge and drawing their hearts towards Heaven. This is the greatest type of generosity of all : he who gives of himself to a person in order to lead him to eternal life in the world to come.
