Next sentence: "The book is written in a simple and lucid style, making it accessible to readers of all levels, from beginners to experienced astrologers." For "written" → documented. "Simple" → straightforward. "Lucid" → clear. "Accessible" → accessible. "Readers" → users. "Levels" → stages. "Beginners" → novices. "Experienced" → skilled.

"Find solutions to life’s problems: The book offers practical remedies and solutions for mitigating negative effects and improving overall well-being." "Find solutions" → obtain resolutions. "Problems" → dilemmas. "Offers" → provides. "Practical remedies" → real-world solutions. "Improving" → uplifting. "Overall well-being" → general health.

"astrology enthusiasts" → same pattern.

Starting with the first sentence: "With the advent of digital technology, it has become easier to access and download books in PDF format." The terms here are "advent", "digital technology", "easier", "access", "download", "books", "PDF format". For each of these, I need to think of three synonyms or similar terms. For example, "advent" could be replaced with "emergence", "introduction", "arrival".

Proceeding sentence by sentence, making sure to replace each word with three synonyms. The user emphasized that the result should only include the rewritten text with the synonyms in the specified format. Let me ensure that I don't miss any words and that the structure is correct. Also, the user wants the text only, no extra explanations, just the result.

First sentence: "“Kairegai Jothidam” is a renowned astrology book written in Tamil, which provides in-depth knowledge on various aspects of astrology, including predictions, interpretations, and remedies."

I'll check each to ensure they make sense in context and that the options are synonyms. Let me verify that the proper nouns are correctly skipped and that each variant flows naturally in the sentence. Once confirmed, I'll format the response as specified.

Then in the question: "What is Kairegai Jothidam?" → nothing to replace.
