After searching google for a while, I have stumbled upon this article.
To my surprise, I found the following statement:
I tried to google more about this and how it works, but everything was filled with many confusing terms, or didn't reveal much.An adherent, therefore, does not have to give up bad habits such as drinking alcohol or smoking right away in order to begin one’s work on the path; one only has to commit to following the path and the desire to engage in unhealthy and damaging behaviors will steadily lose their allure. Instead of distancing one's self from desire, one steps toward and through it, shedding one's attachment as one proceeds in the discipline.
Now, I am living very responsible and don't abuse life, so my question stems from such a sharp contrast between Therevada/Mahayana and Vajrayana.
Can someone please explain to me how does Vajrayana differ and what kind of practice leads them to Kensho?
