The Self is here and now. It is the only reality. There is nothing else.
The dreary days are also spiritual. The days when we have self doubts; the days when our pain body gets activated; the days when we regret the past or fear the future. Be one with every moment; be one with every mood and just see what happens. No matter what, no matter how the self might feel about the situation, life always offers us an opportunity for Self realization.
