You can grow/evolve quicker if you have other people around you to mirror back to you your ideas, beliefs and who you are being. You get constant feedback. You can then make adjustments and test them again. Isolating yourself may be more comfortable, but you miss out on the catalysts created from being around others and your growth will be slow. You only see your ideas from your perspective without them being tested against the backdrop of other people’s perspectives. Testing your ideas on others gives you the opportunity to balance them and bring more love and light to them.
If you put your beliefs and ideas up against the entire world, you have everyone in the world acting as your mirrors. If your beliefs work for everyone in the world, then you have a very advanced set of beliefs that are likely more oriented to high densities.
