Which One to follow since there are 100s of Scriptures? 

SRILA PRABHUPADA SAYS: 

“As the Mahabharata says, “tarko 'pratisthah srutayo vibhinna” ,  that is:  “ Mere logic and argument can never come to a firm conclusion, and due to different countries and different circumstances, one scripture is different from another. Then  “nasav rsir yasya matam na bhinnam”:  

That is : As far as philosophical speculation is concerned, one philosopher puts forward some theory, then another philosopher puts forward another theory, and the theories always contradict each other. Unless you defeat another philosopher, you cannot be a famous philosopher.  That is the way of  philosophy. 

Then how can one learn the conclusive philosophical truth? That is  stated: dharmasya tattvam nihitam guhayam. The secret of the religious process is lying within the hearts of the self-realized souls. Then how do you realize it? 

“Mahajano yena gatah sa panthah”: That is : “You have to follow in the footsteps of great spiritual personalities”. 

Therefore we are trying to follow Lord Krsna and Lord Caitanya. That is perfection. You have to accept the injunctions of the Vedas, and you have to follow the instructions of the bona fide spiritual master. Then success is sure”.
