For a good, pure devotee, any time is a good time, as their intent is always good. There is no bad time as for such people as their mind is filled with noble thoughts.
Only when one has some good and some bad in the mind, the concept of good, auspcious time (Muhurtam) comes into relevance. When you are always good, how can there be a bad time (Durmuhurtam)?
Everything was created by God. Can you call the time created by God as bad? At the same time, you should not say all times are good. But as long as your intent is strong and pure, the concept of auspicious time (Muhurtam) is irrelevant. However if there is any flaw in the resolve (Sankalpa) or if you harbour any doubts, then it is imperative to choose the auspicious time. You then try to investigate if you started at a bad time.
When a person contracts an ailment, his family members should immediately look for a cure. Some foolish people go about thinking why they got the ailment, instead of treating it. The person may lose his life by then.
Thus, if the resolve is strong and true, even what is done at a so called inauspicious time, will bear good fruits. A man can normally see up to 3 feet distance even in darkness. But if his mind in filled with doubts, even in broad daylight, he can only see darkness. You have vision, there is light, and yet you did not see! It means your mind is not alright. If your mind is good, inauspicious time has no significance.
Now comes the question- what is to be done if hurdles crop up during the process of completing good deeds.
The answer for that is- You should practice. You should go on with your attempts. That is why in the Bhagavat Gita it is said that when there are testing times, you must be firm and keep on practising. Steady, consistent practice is essential. Do it like Ekalavya. Do not lose hope.
