When there is a favorable condition we are very often afraid that it may pass, but when there is an adverse condition we do not generally think that it will pass; we think that it will last for ever. This comes from fear, from agitation, from the desire to get out of this condition, and thus we lose even hope, the only source that keeps us alive. When we see the nature of life, and how from morning till evening everything changes, why should we not keep the hope that an unfavorable condition will change and turn into a favorable condition?
