I use this specifically as a thesaurus. If you want to explore different tactics (or Meisner “doings”), I think this book is an incredibly useful tool.
Your Meisner teacher, including mine, will probably tell you not to get this book (god forbid you use a word that may not have originated from your gut!). But I actually think it’s even MORE powerful with Meisner bc it offers roots for exploration of a more colorful spectrum of doings.
For example, are you sick of saying “You’re laughing” or “You’re relaxed” in repetition? After exploring synonyms, you may find they’re not just laughing, they’re actually delighted or cheerful. Are they relaxed, or are they actually content or cheerful? I think that specificity is incredibly useful and true to Meisner’s goal of “be accurate”. By just reading this spectrum of behaviors on the page, you’ll start feeling and recognizing them in your scene partner and pulling them “from your gut” on stage.
That being said, you can do that with any thesaurus or simple internet search, you definitely don’t need this book at all to play with this.
