If we examine our life we will discover that most of our time and energy is devoted to mundane activities, such as seeking material and emotional security, enjoying sensory pleasures, or establishing a good reputation.
Although these things can make us happy for a short time, they are not able to provide the deep lasting contentment that we long for. Sooner or later our happiness turns into dissatisfaction, and we find ourselves engaged in the pursuit of more worldly pleasures. Directly or indirectly, worldly pleasures cause us mental and physical suffering by stimulating attachment, jealousy, and frustration. Moreover, seeking to fulfil our own desires often bring us into conflict with others.
If true fulfillment can't be found in worldly pleasures, then where can it be found? Happiness is a state of mind, therefore the real source of happiness lies in the mind, not in external circumstances. If our mind is pure and peaceful we'll be happy, regardless of our external conditions, but if it is impure and unpeaceful, we will never find happiness, no matter how much we try to change our external conditions.
The purpose of meditation is to cultivate those states of mind that are conducive to peace and well-being, and to eradicate those that aren't.
Only human beings can do this. Animals can enjoy food and sex, find homes, hoard wealth, subdue their enemies, and protect their family; but they cannot completely eliminate suffering and attain lasting happiness. It would be a great shame if we were to use our precious human life only to achieve results that even animals can achieve. If we wish to avoid such a wasted life and fulfill the real purpose of being born human we must devote ourself to the practice of Lamrim.
