Wisdom Teachings - Sat Yoga, Costa Rica

Student Question: I wanted to know if you could elaborate a little bit more on the difference between sanskaras and past lives because I mentioned to a student here that it might be interesting to study my past lives, but what for? What purpose would it serve in accelerating my growth? And it was mentioned that it is actually more correct to say that sanskaras reincarnate rather than saying that we have past lives.
