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.
