To be a spiritual advisor is not like getting a PhD or being a professor where after completing your study you become a spiritual advisor .
In fact don’t ever try to be a spiritual advisor or a lama, it doesn’t work like that. Just keep practicing with your life responsability and with your meditation training practices, then it will come naturally .
When you have a true practice as a student of Buddhism, you will find yourself naturally able in real situations to share some spiritual advice. It will come from your truthful and happy personality, you will share your life understanding and your natural warmth with anyone around you.
