Is Toska = 'Zapurza' (झपुर्झा)?

Today I read here about word Toska.

Vladimir Nabokov, cited in A Field Guide to Melancholy by Jacky Bowring:

"Toska - noun /ˈtō-skə/ - Russian word roughly translated as sadness, melancholia, lugubriousness.

No single word in English renders all the shades of toska. At its deepest and most painful, it is a sensation of great spiritual anguish, often without any specific cause. At less morbid levels it is a dull ache of the soul, a longing with nothing to long for, a sick pining, a vague restlessness, mental throes, yearning. In particular cases it may be the desire for somebody of something specific, nostalgia, love-sickness. At the lowest level it grades into ennui, boredom."

Is there a single Marathi word for this?

Probably yes, Keshavsut (केशवसुत) invented word : Zapurza (झपुर्झा) from his poem of the same title:

"
हर्षखेद ते मावळते,
हास्य निवालें
अश्रु पळाले;
कण्टकशल्यें बोंथटलीं,
मखमालीची लव वठली;
कांही न दिसे दृष्टीला,
प्रकाश गेला,
तिमिर हरपला;
काय म्हणावें या स्थितिला ?-
झपूर्झा ! गडे झपूर्झा ! १

हर्षशोक हे ज्यां सगळें,
त्यां काय कळे ?
त्यां काय वळे ?
हंसतिल जरि ते आम्हांला,
भय न धरुं हें वदण्याला :-
व्यर्थीं अधिकची अर्थ वसे,
तो त्यांस दिसे,
ज्यां म्हणति पिसे,
त्या अर्थाचे बोल कसे?-
झपूर्झा ! गडे झपूर्झा ! २
..."
