Sharp Tongue Sanskrit

When I did the life bliss engineering program (LBE) one day Swamiji talked about how the language Sanskrit makes your tongue sharp. It was sort of a hard concept to understand. He was saying that when your you've is shape you are able to a) form any words so easily and b) make good comebacks or rather be able to respond quickly and smartly thanks to the help of a sharp tongue. The best analogy I can give is when you do yoga and/ or work out the body becomes supple and strong. If some one where to just take one short walk a day, yes they are using their body, but the body will not develop muscles or become very strong. That's basically like chanting in Sanskrit versus just singing any old song. Sanskrit physically makes your tongue strong, and "sharper" if your body has good muscles and is well built you could just jump up any time, take a run and it would be easy but for someone who only takes one walk a day it would be harder to just jump off the couch and take a run.
Well Swamiji explained this whole thing to us (although not with the analogy I did) but I was just a little confused and didn't understand how just by chanting a certain language your tongue could be sharp.
At the temple we do a pooja to Swamiji's paadukas, and to him on the TV screen as we are connected live (like skype) the first time we did this pooja I just happened to sit next to one of the people who where chanting the mantras. She had a mantra sheet and out of curiosity I read it and started to chant with her. Not very well of course but it was only my first time. Over the past few weeks we have started to do the pooja more and more, everyday in fact. Chanting is now one of my main jobs, I still stumble over some of the words, but I improve each day. The thing I noticed a few days ago is what Swamiji said that one day in LBE is happening to me! I can literary feel my tongue getting sharper. Stronger with each time I chant. The funny thing is I have chanted the Guru Pooja mantras for about two years and I have never had this feeling. But now I am having it, I can see the side effects too words just roll off my tongue so easily. I was good at talking before, but I feel I am improving! So that's just an interesting thing I wanted to share with you all, talk to you guys soon!
