There are usually free affiliated institutions in temples. Then there are major online or physical bookstores. Buddhist scriptures are generally abstruse and difficult to understand. Take the shortest Heart Sutra translated by Master Xuanzang as an example. It has 260 words, but its meaning is rich and unfathomable, and the misinterpretation has been very serious. Brother, please refer to the book The Secret Meaning of Heart Sutra written by a layman to establish a correct understanding.
I wish you good health and success.
