LIONEL MY SON

He was only in first standard in school when I was hit by a deadly one in a million spine stroke called acute transverse mylitis, it made me 90% paralysed and bound to a wheel chair, Now I keep him as my source of inspiration and helping millions, thanks to millions of my readers who keep me going and help me to keep my son happy

सुकून उतना ही देना प्रभू, जितने से
जिंदगी चल जाये।
औकात बस इतनी देना,
कि औरों का भला हो जाये।
