What was the specific goal of Das Ganu's book, the 'Ishavasya-Bhavartha-Bodhini,' and why did he get stuck while writing it?

As detailed in Chapter 20, the goal of Das Ganu's 'Ishavasya-Bhavartha-Bodhini' was to create a commentary on the Ishavasya Upanishad for people who were 'ignorant of the Sanskrit language.' He intended to explain the meaning of each word through simple Prakrit language using Ovi verses. He got stuck because, while he could perform a literal, word-for-word translation, he failed to grasp the 'internal secret' or the deep, profound meanings within the Upanishad. This lack of deeper understanding meant his mind 'found no joy' in the work, bringing his progress to a halt.
