Srimad-Bhagavatam has many tikas, or commentaries, following the parampara system, but Sridhara Svami's is first. The commentaries of all the other acaryas follow his. The parampara system does not allow one to deviate from the commentaries of the previous acaryas. By depending upon the previous acaryas, one can write beautiful commentaries. However, one cannot defy the previous acaryas. The false pride that makes one think that he can write better than the previous acaryas will make one's comments faulty. At the present moment it has become fashionable for everyone to write in his own way, but such writing is never accepted by serious devotees. Because of false pride, every scholar and philosopher wants to exhibit his learning by interpreting the sastras, especially Bhagavad-gita and Srimad-Bhagavatam, in his own way. This system of commenting in one's own way is fully condemned by Sri Caitanya Mahaprabhu. Therefore He says, 'artha-vyasta' likhana sei. Commentaries written according to one's own philosophical way are never accepted; no one will appreciate such commentaries on the revealed scriptures.
