Lama Zopa Rinpoche

And in the same way, just as you become the deity, the environment appears to you in the
form of the mandala—that is what you visualize now. That is the purity of place. Visualizing
the mandala of the deity purifies ten million eons of negative karma. On top of that, when
you enter the mandala visualized in the sadhana—this perfect environment you will achieve
in the future—that also becomes the most unbelievable purification.
In the future, when you become a buddha, you will be able to do unbelievably extensive
deeds. Sending even one beam of light to sentient beings will liberate them from suffering.
That is what you will be able to do and so, in your sadhana, you visualize that as happening
now. That is the purity of deeds.
When you become a buddha, due to your mind developing into a totally pure, holy mind,
without even subtle obscurations, you are able to enjoy numberless completely pure
offerings. This is what will happen when you become a buddha and this is what you visualize
now. And again you collect unbelievable merit. That is the purity of offerings.
In the Paramitayana, completing the collections of the merit of transcendental wisdom and
the merit of virtue, the causes of the dharmakaya and rupakaya, takes three countless great
eons. But here, in tantra, especially in Highest Yoga Tantra, because of great skill, meditating
on the path similar to the four complete purified results becomes a path to achieve
enlightenment in one lifetime.
That is why we need to practice tantra, and especially Highest Yoga Tantra, right now,
without delaying even a second. Only when we achieve full enlightenment, the state of the
omniscient mind, can we free the numberless sentient beings from the oceans of samsaric
suffering and bring them to full enlightenment. If we achieve the omniscient mind, we can
do that perfectly, without the slightest mistake. Even an arhat or a bodhisattva on the tenth
bhumi cannot do that.
