Hey We can connect this with the aspect of Purim Koton (which is when the above mentioned Maamor starting with the verse Vekibel Hayehudim was actually delivered) in which the concept of טוֹב־לֵב מִּשְּׁתֶה תָּׂמִּיד “He who has a cheerful heart always has a feast” is emphasised.
Concept of:
That which it says in the Possuk in Mishlei (15:15) כָּׂל יְּמֵי עָּׂנִּי רָּׂעִּים, וְּטוֹב לֵב מִּשְּׁתֶה תָּׂמִּיד “All the days of a poor man are wretched, but he who has a cheerful heart always has a feast”.
Emphasised:
Because there are two opinions whether to increase in drink and in joy on Purim Koton, and the Remoh compromises that one should increase in his meals so as to satisfy the stringent opinions and concludes with this same verse: טוֹב־לֵב מִּשְּׁתֶה תָּׂמִּיד .
It is brought down in the Talmud that the verse: טוֹב־לֵב תָּׂמִּידמִּשְּׁתֶה refers to someone who has a broad mind. This means that when one has a broad mind which is the level of wealth, which symbolises serving Hashem beyond logic without ulterior motive, then he has [achieved this consciousness of parity, whereby all things are considered equal] and because of this sense of ‘equality’ he is constantly in Simcha. Which is טוֹב־לֵב מִּשְּׁתֶה תָּׂמִּיד.
And similarly, with regards to Mesiras Nefesh as was explained earlier, that when a person is willing and ready to be Moser Nefesh, then all obstructions and Hindrances fall away, so that he will actually not need to be Moser Nefesh[!]
Talmud:
Tractate Bova basra (145B) רבי יהושע בן לוי אמר כל ימי עני רעים זה שדעתו קצרה וטוב לב משתה תמיד זה שדעתו רחבה “Rabbi Yehoshua ben Levi says: “All the days of the poor are terrible”; this is referring to a person of impatient disposition. “And for the good-hearted it is always a feast”; this is referring to a person of patient disposition”.
He will only, טוֹב־לֵב מִּשְּׁתֶה תָּׂמִּיד for all time have a cheerful heart, since through his Mesiras Nefesh all the obstacles will be removed, and thus will he draw down everything in a visible and tangible way.
