I have tried meditating many times and I find it terribly difficult to keep a still mind even for 5 minutes! I feel like there's a monkey in my head jumping around!
But what is for sure is that things get better with time and practice. Of course one has to do meditation correctly to progress. Take for example, a car is usually safe to drive, but when done without mindfulness or drunk, then it becomes a recipe of disaster!
First of all, we must understand the types of meditations we can engage in. There are two types of meditation which is 'Analytical' and 'Concentration'. So what's the difference between these two meditation?
In Analytical meditation, we use our logical reasoning to examine the teachings to determine ourselves whether or not they are true, to remove any form of doubt, and to come to a clear understanding and unshakable conclusion on the topic in question.
In Concentration meditation, we learn to focus our mind single pointedly on a mental object until our mind can rest effortlessly on that object for hours or even days at one single time.
Although they are quite different in nature, these two meditation, they both share a sameness and support each other. An example of analytical meditation is when Phabongkha Rinpoche meditated on the headings of the Lamrim that His holy Guru gave him, until he came to an unshakable conclusion of the truth.
So why put ourselves through this "excruciating" practice? Because it is without a doubt that all of us wish only for happiness... and it is through meditation do we get indepth, unshakable understanding in Dharma. After all, Dharma is the only thing in this world that brings pure, untainted happiness just as proven by all the great Mahasiddhas and Buddha himself.
