The only responsibility of an enlightened Master is to liberate the souls. We should go and find an enlightened Master or a living Buddha before we can be liberated in this life time. Since the ancient times, all the Masters who came down to this world have only one liability, i.e. to make people enlightened immediately and liberated in this life. They have no other job. The so-called real Master is the one who has attained  enlightenment and can transmit it  to  others. All  true Masters coming down to this world offer people only immediate enlightenment and liberation in this life.

No matter how famous and how powerful a Buddha is, once he/she left this world, he is gone. He/she goes to another realm and teaches other types of beings who might be his/her past disciples and have not attained a high level yet and stay in that world. He/she continues to teach these disciples there. When reading classic scriptures, we may feel satisfied to know about the realms described in the scriptures and may think that only he/she and his/her disciples can attain and enjoy those realms. Then we are lost there and forget that the Master has mentioned that we should go and find an enlightened Masters or a living Buddha and then can we get liberated in this life.
