Things that make you feel good are good for your overall vibration. The vibes you feel right now are the ones you are putting out to the world, that everyone else can feel, and will then be reflected back to you. It's like karma, but worse, because you're only being a dick to yourself, and in return, shitty things happen to you. If you are feeling anything less than joy in this moment, you should try to raise your vibe a bit before attempting to take on a spiritual journey. If you go into your first meditation feeling like you're not worthy of joy and wonderful things, it might be very difficult for you to feel like you're succeeding. So, before you get started... watch something hilarious that makes you smile.
