Dear Rinpoche, in the last video you said something like 'You don't only attain shamatha, but even samadhi and then you can take birth in form realms…'
1. What is difference between shamatha and samadhi, and most of all, do I need shamatha or samadhi to fly ;)?
2. Can calm abiding harm my inteligence?
Let me explain…I had a brilliant idea of doing calm abiding when I receive teachings in Tibetan with consecutive translation. Since I don't understand Tibetan, I'd normally do nothing special during 3-7 minutes of teachings in Tibetan, so I decided to use that time for calm abiding. Like this, I alternated 3-7 min. calm abiding sessions with 3-7 min. simultaneous interpreting form IT to EN. I presumed calm abiding would improve my concentration and make my interpreting even better. I was wrong! After 3-7 min. calm abiding, I found my mind slower to grasp concepts, slower to produce speech, it sometimes even felt like my hearing was impaired… So, I wonder if I am doning sth. wrong or this is normal calm abiding meditiation side effects? And if in that case it weren't better to complete one's studies first and then do calm abiding etc.? What do you think?
