Only Medicine for the present world - Namakeerthanam. Only way in Kali is namakeerthanam and the book which describes it is the Srimad Bhagavatham.

The greatness of Srimad Bhagavatham is that wherever the parayanam of Srimad Bhagavatham is being performed and where it is listened to, in that place, Kali will never come. The present world in which we live is Kali, Kali meaning "Kalmasham". There is a lot being told in many discourses on how the people would be in Kali and how they would act. The only medicine for Kali is Srimad Bhagavatha parayanam. Srimad Bhagavatham also tells us about the significance of Namakeerthanam. Due to the influence of Kali, even a suddha Atma, who had been with the lord in his birth itself, like Parikshith was subject to a wrong doing by putting a dead snake around the neck of a sage. Even playfully, Kali should not get associated with anyone.  

Parikshith put the snake around the neck of Maharishi Sameekar and as a result his son Sringi pronounced a curse upon him after which he listens to the Srimad Bhagavatham for 7 days. Since he had a curse as a result of this Kali dosha, he listened to Srimad Bhagavatham which removes this dosha. That in itself is testimony to the fact that Bhagavatham will remove the doshas of Kali. 

Once the Srimad Bhagavatham was hid by Kali. It is known that one who is doing good in Kali will get lot of bad happening to them. If one is suffering a lot, it does not mean he is bad and if one is living in the lap of luxury, we cannot brand him as good even. In Kali, one cannot differentiate between the good and bad , either in suffering or comfort as we see from Mahabharata, the good pandavas suffered whilst the bad kauravas, duryodhana and his people were indeed in comfort. Those who believe in God will suffer a lot but they will never leave God, that's their greatness. Only way in Kali is namakeerthanam and the book which describes it is the Srimad Bhagavatham.
