Everything is the universe is energy, including humans and that energy moves in a circular fashion. The difference of one form of energy from another is the speed of its vibration. We know light has a very high frequency and a rock vibrates at a low frequency. Humans vibrate at different frequencies. The frequency at which humans vibrate draws in like energy ( ‘chemistry’) or repels unharmonious frequencies.
Whatever your challenges are right now, they develop in you a capacity for resolving them, albeit they may seem difficult. Avoid the tendency to fight against or avoid them. Simply realize that life has challenges and that each challenge offers you the opportunity to stretch and grow.
