Namaste. Pls help me to understand the difference between Bhasha Pravesh course and Pravesh Beginners course. I registered on the website of Samskrita Bharati for the Pravesha level of the correspondence course and received the book from them. But now I see there is another book on their website which is titled Bhasha Pravesha. What is that? Is that from a different course? Also, there are two series of video lectures on your Youtube channel, titled Bhasha Pravesh course and Pravesh Beginners course. Which of these corresponds to the Pravesha course of Samskrita Bharati? I've seen the lectures from both of them but they don't exactly match the subject as discussed in the Pravesha book. Kindly advise. thanks.
