The Vajra Prajna Paramita Sutra
4. The wondrous practice of non-abiding
“Moreover, Subhuti, as to the act of giving, a Bodhisattva should not dwell anywhere when he gives. He should not dwell in forms when he gives, nor should he dwell in sounds, smells, tastes, tangible objects, or mental constructs when he gives. Subhuti, a Bodhisattva should give thus: he should not dwell in marks. And why? If a Bodhisattva does not dwell in marks when he gives, his blessings and virtues are immeasurable.
“Subhuti, what do you think, is space in the east measurable?”
“No, World Honored One.”
“Subhuti, is space in the south, west, north, or in the intermediate directions, or above, or below, measurable?”
“No, World Honored One.”
“Subhuti, the blessings and virtue of a Bodhisattva who does not dwell in marks when he gives are just as immeasurable. Subhuti, a Bodhisattva should only dwell in what is taught thus.

The most important thing is that each time we read it; it plants a seed, an imprint to realize emptiness. The more you read it, the more imprints it leaves on the mind. So it becomes easy to realize emptiness. It becomes quicker and quicker to realize emptiness in this life. If not in this life, then quickly in future lives. Then by developing this wisdom, you achieve the wisdom of great insight unified with shamatha. You can meditate on emptiness unified with shamatha and are able to derive rapturous ecstasy of the body and mind. Then through this, you are able to achieve the direct perception of emptiness that ceases the defilements and the disturbing thoughts; first, by ceasing the intellectual all obscuring thought, and then the simultaneously born one. That is how you achieve liberation, by ceasing that completely, including the imprint, the seed. Then, with bodhichitta the direct perception of wisdom ceases even the subtle defilements and you achieve omniscient mind. Then, you are able to do perfect work for sentient beings. You are able to bring all sentient beings to enlightenment. This is the goal of our life: to bring sentient beings to enlightenment. When that happens, when we are able to do that, our goal is achieved.
