We should not let our minds of doubt weaken and deter us. Furthermore, we should not be afraid of or worry about karmic obstructions. They provide us with opportunities to change and improve ourselves. If we trip and fall over these obstructions, it is all right. We should get up and continue on and try to learn from it. If we fall again, we should get up again, no matter how many times it takes.
