Offering of Dharma is particularly important. If we are given two choices: 1) we can release all the fish in the market free of charge on condition that we do not recite the Buddha’s names for them or feed them nectar pills; 2) we can recite mantras, feed them nectar pills and bless them with the text of ‘liberation upon wearing,’ but we cannot buy them to set them free. Which one should we choose? Make sure it is the latter. 

- Quote from The Right View, "Liberating Living Beings"

All the Buddhas in the past including Shakyamuni Buddha, after having aroused bodhicitta, had vowed to deliver all sentient beings to liberation before attaining Buddhahood themselves. Yet they have already attained Buddhahood while we still remain in samsara. Did all the Buddhas break their vows? No. The Buddhas’ vows were made out of their deep compassion for the sentient beings. By the supreme power of the grand vows, they were able to swiftly attain Buddhahood. Whereas the thought that is constantly being turned over in our minds is usually just our own welfare, which explains why we are still struggling in samsara as yet. This clearly demonstrates that the key to attaining Buddhahood rests squarely on nothing but one’s altruistic aspiration.

About longevity, the following story makes a point. A disciple of the Venerable Atisha violated the precept and died after getting involved in a village dispute. Upon hearing the news, the Venerable Atisha noted with sorrow, “If he died three years earlier, he would have died a bhikkhu adept in the Tripitaka.” This means that if he died three years earlier, he would have died a bhikkhu with pure vows and of great knowledge in the Tripitaka. But he died a different person with a tainted reputation three years later. Therefore, having longevity is not necessarily a good fortune. Some beings may end up committing more negative karma with extended life span.

- Quote from The Right View, "Liberating Living Beings"

We have all committed incalculable karma of killing lives since beginningless time. Even so far in this lifetime alone, we have generated enough such karma to send us to the hell realm. And the best way to counteract this karmic effect is to liberate living beings. At the same time, we must also resolve by making a pledge not to intentionally kill or hurt ANY sentient beings ever again. With such determination, all negative karma associated with killing lives will indubitably be purified. In case one’s resolution is not yet as firm, the pledge can be made on account of the selected beings of one’s choice. For example, one can vow never to kill snakes or weather loaches again from now on. When this vow is made and the beings are subsequently freed, one’s specific karma of killing snakes or weather loaches from beginningless time will then be purified, but that of killing other kinds of beings stays.

The use of nectar pills is not emphasized in exoteric Buddhism, but very much so in Vajrayana. Most of the nectar pills were originally handed down by Guru Rinpoche and later discovered by real tertons, finders of terma (hidden treasures). It should be noted that not all nectar pills have beneficial effect. Some of the so-called nectar pills are not only devoid of any merit but can also bring harm if taken, such as preventing one from attaining liberation in future life and creating hindrances to liberation.

Where do these harmful pills come from? Some are from tertons who are actually impostors and some are concocted by demons to hurt sentient beings. At times, genuine nectar pills, after being handled or made by persons who have broken samaya vows, can also be tainted. As Guru Rinpoche did not leave behind many nectar pills, accomplished masters, after retrieving them, will mix them with other nectar and medicinal herbs, then bless the pills through meditation and mantra recitations. If during this process there is one samaya violator among the attending practitioners, the pills will get tainted.

Therefore, close attention is needed when administering nectar pills. As ordinary beings, we cannot tell the real from the fake ones with the naked eye. The only way is by examining whether the pills came from a pure source. This is a very important step.

In general, people all long for wealth, longevity or certain magical power. But, in the long run, it is very difficult to say whether these are really good for a practitioner or an ordinary individual. You are all familiar with the story of Devadatta. If he had not had supernatural power, he would not have committed two of the Five Great Offenses leading to the avici hell. He subjugated the king with his supernatural power, convincing the king of his might and to obey his words. Together, they committed a great deal of the offenses that led to the avici hell.

On the other hand, does it make sense to swear never to kill dinosaurs from now on? You may think that it is meaningless, since there is no dinosaur to be killed even if you want to. But it does make sense still. Dinosaurs once existed, which means we surely had the opportunity to kill some in those lifetimes. As explained above, when such vow is made, one’s karma of ever having killed dinosaurs will be purified, but not those that involved killing of other beings. If we vow not to kill any sentient beings, our karma of killing all kinds of beings can be purified. If the vow is made for the sake of particular beings, our karma of killing those particular beings can be purified.

- Quote from The Right View, "Liberating Living Beings"

Liberating living beings can also prevent some evil karma. Take the example of freeing one fish. First, if the fish vendor sells the fish to a restaurant, he will have committed karma of killing that fish. By buying the fish from the vendor, we stop that from happening. Second, if we do not buy the fish, the cook at the restaurant will kill it. We prevent the cook from committing that karma with our purchase of the fish. Third, the customers eating the fish are also guilty of killing. By buying the fish, we prevent karma of killing for the third time. As the fisherman would not know at the time of catching the fish if it was to be liberated or killed, his evil karma, if any, may not be prevented by our purchase. But the other three can all be avoided. When liberating beings, to make every endeavor not to hurt them as well as the feelings of other people is in fact benefiting sentient beings already.

- Quote from The Right View, "Liberating Living Beings"

We may also encounter difficulties when liberating beings, e.g., extreme weather conditions, fatigue, insect bites, interferences from others, etc. When these happen, we should contemplate that they are there to purify our negative karma. Or, we can practice the teachings of The Way of the Bodhisattvas to exchange our own well-being for other’s suffering. That is, we willingly endure all the hardship and inconveniences on behalf of other beings. It may seem just a small sacrifice on our part, but great merit can be accumulated this way as well. Therefore, we should practice patience with all physical discomfort and hardship. By the same token, when others make unreasonable demands on us or cause outright trouble, we should neither argue nor be angry with them, just accept their behavior with equanimity. This is the perfection of patience.
