Swami Vivekananda alternative.

Namaste! I have recently enrolled in an online course on Yoga, Ayurveda and Mantra conducted by Pandit D David Frawley, it is quite a robust course (Subjectively speaking) and I would like to accompany it with some reading to allow me to keep it from feeling like “School”. I have read The collective works of Vivekananda and I feel like these are the most profound teachings I have ever received, his perspective on myriad topics are always (to me) just pure beautiful truth and I feel like I will always come back to him after letting it breathe a while. So the question…are there any other book recommendations by learned teachers in the same kind of style? Many thanks!
