How to practice Dzambhala
Since we all have such a karma to achieve wealth, now we are practicing Dzambhala. One of the ways it can help us to have the wealth to benefit others is by activating those seeds.
Generally, like a seed need a moisture or a water as a condition, our seed to have the wealth also needs a sort of a water or a condition. So practicing Dzambhala can be a perfect condition to activate the seed to become rich.
We all have accumulated many types of karmas from the beginningless time of life. And so we all have certain karmas to have the wealth to benefit others who are sick, who are poor, who are not in a condition, who need the wealth and support to practice dharma. So this is the reason and the motivation also should be something like that when you practice Dzambhala.
