Hi Nacho:
I agree with Gallen that consistency is the key no matter if you practice level 1 or 2, or as I do, a combination of both. After practicing Level 1 (off and on) for almost two years, I recently transitioned into level 2. I still very much enjoy Level 1, and find that alternating days between levels 1 and 2 really works well for me. I also alternate my mediations between small universe and self concentration. For me, practicing both levels simultaneously, has enabled me to achieve more consistency in my practice.
