All the problems that you face in life are because you attach over importance to the events. The events grow bigger while you remain smaller. Say for example, you are riding a motorbike on a busy motor way and in front of you there is another vehicle emitting exhaust fumes. You have three options.
As in the first case, most of you stick on the events and are miserable,
like inhaling fumes throughout you journey.
In the second case, you don’t, get permanent relief, as another bigger vehicle might come in front of you. Like that, running away from events is not the permanent solution.
However, wise people use their skill and grow over the events. If the vehicle is in perfect condition, the skill is effective. Conditioning the vehicle is sadhana or practice. And skill is the grace of the Guru.
The mistake that you have made in the past have made you humble; you need not make mistakes in the future to become humble.
