It was during the winter of year 2019 when Covid struck. In a matter of days, the virus stealthily spread at an alarming, breakneck speed all over the world, leading to devastating loss of lives and crippling of economies. Like all biological entities, it had to have a purpose. To search for that purpose, Prof. Sujata Sharma of All India Institute of Medical Sciences, New Delhi undertakes a memorable expedition on her imaginary spaceship into the solar system. She encounters all the nine heavenly bodies of 'Navagraha' and their corresponding Warriors in White in AIIMS and other leading hospitals of India. Using a heady combination of molecular medicine, astronomy and Vedic astrology, she understands the nuances and eccentricities of the virus. At a celestial level, the expedition begins from the Sun, Prof Randeep Guleria and progresses to other planets and warriors, eventually spanning the entire galaxy. At a terrestrial level, the journey starts from New Delhi to Chandigarh via Bengaluru, zipping through Mumbai and Varanasi, onwards to Noida and finally ending back in Delhi. This exhilarating and inspiring voyage in the middle of the deadliest pandemic of the world helps her to finally discover the elusive Covid's purpose.
