Thank you. Yes thats the practice that im talking about. I im very intrested in that practice and the lama said its good for practicing during dreams wich is good for me because i tend to have a couple of lucid dreams a week and have discusse it with my lama. On the other hand i dont think ill have the oportunity to invest time in this practice as im doing other practices and i dont want to get over my head. So i gess its like you said, just for the karmic seed. I guess this will happen a lot. Beeing afraid of "leeting the train go", ill just hope that the oportunity will present itself again in the future.
Im still interested in learing more about the practice if someone has expirience on it.
Sorry about my spelling mistakes, i dont have a corrector on this pc.
