My brother's son marriage was planned. But just 4 days before the lockdown was declared and the function was postponed at the last minute. All arrangements were made and there is some wastage of money because of that postponement.
That is why in our scriptures, it is very clearly mentioned that our duty is to work hard but result is not in our hands. It could be in our favour or not in favour and it will be known only in a time in future. Call it fate, luck, or destiny but there is no way to explain it.
Knowledge is power.
