Let me check each line. The first line is "ଷାଠର ସୋମବାର ଵ୍ରତ କଥା ଇନ୍ ଓଡିଆ". "ଷାଠର" is a number, 64. Proper nouns? No, it's a number. So I need to replace "ଷାଠର" with synonyms for the number 64. Wait, numbers aren't usually replaced, but the user said "update all words". Hmm, maybe it's a typo. Maybe "ଷାଠର" is a transliteration issue. Let me check the original text again. Oh, wait, the first line says "ଷାଠର ସୋମବାର ଵ୍ରତ କଥା ଇନ୍ ଓଡିଆ". Maybe "ଷାଠର" is actually "54"? Wait, in Odia language script, numbers are different. Let me confirm. The Odia script for 54 is "ପଞ୍ଚାଶତ୍". But "ଷାଠର" is "54"? Wait, no. Let me check. "ଷାଠର" in Odia script is "59"? Wait, not sure. Maybe the user made a mistake here. Alternatively, maybe "ଷାଠର" is a name, but it's probably a typo. Alternatively, maybe it's a place name. But in the context, the first line is "ଷାଠର ସୋମବାର ଵ୍ରତ କଥା ଇନ୍ ଓଡିଆ" which translates to "54 Mondays Vrat story in Odia". So maybe "ଷାଠର" is supposed to be "54", but written in Odia script. So the word to replace is "ଷାଠର", which is the Odia script for 54. However, as per the user's instruction, proper nouns stay. But 54 is a number, not a proper noun. So I need to find three synonyms for "54" in Odia. But numbers don't have synonyms. Hmm, maybe the user intended "54" as a quantity, but it's unclear. Maybe the actual number is 54, but in the text, it's written as "ଷାଠର". Let me think. If the word is "ଷାଠର" (54), and the task is to update all words with synonyms, how to handle numbers? Since it's a number, it won't have synonyms, so maybe leave it as is. Or perhaps it's a typo and should be replaced with the Odia script for 16? Wait, the original text mentions "16 Mondays" in the second paragraph. Wait, let's look again:

3. କଥା: story, saying. Alternatives: ବୃତ୍ତମାଳା

First, I need to identify each term. Let's break down the original text into parts. The first sentence talks about "Sunday fasting saying" (ସୋମବାର ଵ୍ରତ କଥା). The term "ସୋମବାର" is Monday, "ଵ୍ରତ" is fast, and "କଥା" means story or saying. So the term "ସୋମବାର ଵ୍ରତ କଥା" would be "Monday fast saying" in a literal translation. I need to create three variants for each term.

Original text (translated): "The Monday fast is a prominent fast in Hinduism, observed to please Lord Shiva. This fast is observed for 16 Mondays, starting from January to April."

Okay, so I need to take the given Odisha text about the Somvabar Vrat and update all the words with three synonyms each, using the syn1 format. The user also mentioned that proper nouns should stay the same. Alright, let me start by understanding the original text.
