We all want to be happy, that's something we have in common. Each of us has different strategies to achieve it, but what we share is the primary desire to be happy and to move away from discomfort, pain, and suffering.
What can we achieve out there so that happiness in this life is guaranteed?
The guarantee of happiness is merit. Merit means "Positive karma." So, if there is merit, regardless of power or influence, regardless of purchasing power, regardless of the power of your intelligence, you have the power of karma, which is indeed positive karma, and it is the direct cause of happiness.
How do we generate merit in meditation? How do we generate happiness in meditation?
Meditation, on one hand, develops skills, virtues, and mental, affective, and cognitive capacities; but, on the other hand, we actually just want to neutralize all distortions. We consciously improve these qualities to neutralize all layers that are obstructing our nature.
Heaven is here and now, we just can't see it, we're not aware of the pure truth; we're seeing it through conceptual and emotional filters that distort that reality.
