SB 1.1.13

     tan nah susrusamananam
 arhasy anganuvarnitum
yasyavataro bhutanam
  ksemaya ca bhavaya ca
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Suta Gosvami, we are eager to learn about the Personality of Godhead and His incarnations. Please explain to us those teachings imparted by previous masters [acaryas], for one is uplifted both by speaking them and by hearing them.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada : 
 
The conditions for hearing the transcendental message of the Absolute Truth are set forth herein. The first condition is that the audience must be very sincere and eager to hear. And the speaker must be in the line of disciplic succession from the recognized acarya. The transcendental message of the Absolute is not understandable by those who are materially absorbed. Under the direction of a bona fide spiritual master, one becomes gradually purified. Therefore, one must be in the chain of disciplic succession and learn the spiritual art of submissive hearing. In the case of Suta Gosvami and the sages of Naimisaranya, all these conditions are fulfilled because Srila Suta Gosvami is in the line of Srila Vyasadeva, and the sages of Naimisaranya are all sincere souls who are anxious to learn the truth. Thus the transcendental topics of Lord Sri Krsna’s superhuman activities, His incarnation, His birth, appearance or disappearance, His forms, His names and so on are all easily understandable because all requirements are fulfilled. Such discourses help all men on the path of spiritual realization.
