Then your teacher probably has valid reasons for teaching you such. To quote master Shan-tao:

To emerge from one gateway is to emerge from one gateway of blind passion; to enter one gateway according to your opportunities and conditions is to enter one gateway of emancipation- wisdom. In this way, you should undertake practice in accord with your opportunities and conditions and seek emancipation. Why do you obstruct and confuse me with what is not the essential practice corresponding to my conditions? What I desire is the practice corresponding to my conditions; that is not what you seek. What you desire is the practice corresponding to your conditions; that is not what I seek. Each person’s performance of practices in accord with his aspirations unfailingly leads to rapid emancipation.

Practicer, know that if you desire to gain understanding, you will be able to study without obstruction the teaching relevant to the stages of ordinary beings or sages or to the fruit of Buddhahood. If you desire to undertake practice, by all means follow the method of practice corresponding to your conditions. In return for a little effort, you will gain great benefit. Source
