Here is another example from your book. कुशा, the main character girl of your story, might have read about the dissection of Sun-Flower stalk. She might have seen the picture of the dissection and she might have read the procedure and rewrote in her practical sheet (to get initial signature). She might have understood the procedure (intellectual knowledge). However, she got so excited only when she successfully dissects the plant herself. She got skill through the practical knowledge. She can use this skill to human tissues if she becomes a doctor, and earn lot of money out of it. Practical knowledge gives result. Practical knowledge has strength to change inside as well as outside world. Practical knowledge is भावनामयी प्रज्ञा. Rest two knowledge, श्रुतमयी प्रज्ञा and चिन्तनमयी प्रज्ञा are for the preparation of entering to भावनामयी प्रज्ञा. They are pre-requisite of भावनामयी प्रज्ञा. The first two wisdoms are the borrowed wisdoms. Somebody said to you (श्रुतमयी प्रज्ञा) and you got convinced (चिन्तनमयी प्रज्ञा). If you just limited yourself to श्रुतमयी प्रज्ञा and चिन्तनमयी प्रज्ञा, you get nothing out of it except a type of false satisfaction. When you talk to people with your borrowed knowledge, you may get few words of praise. This will keep you happy for few moment; a false happiness! Why false happiness? Because if your audience don’t praise you, you don’t get happiness, if they abuse you will get pain. Your happiness is completely in somebody else’s hand. This is why I told you these first two wisdoms can’t rescue you when you are in trouble. If you are an engineer and know very well how to generate electricity but if you don’t generate electricity, you also have to live in darkness as other who doesn’t know anything about electricity. So, practical know is utmost importance. I am sorry; I took so much time just to say that the practical knowledge is only knowledge that counts. If I use the word wisdom from now on, please understand it as भावनामयी प्रज्ञा, ie the practical knowledge ….knowledge through experience. This is the knowledge which Buddha talks about. This is the wisdom in the language of Buddha.
