Firstly, recite the various Buddha’s names or other mantras to the beings about to be released. According to the scriptures, these beings will be greatly benefited upon hearing the Buddha’s names and mantras. Also make sure that every one of them can hear the recitations. If we recite from afar and dedicate the merit to them afterward, they can be benefited somewhat but cannot obtain specifically the merit of hearing the Buddha’s names because they did not hear the recitations. If we recite within their hearing range, the merit they will receive are twofold: first, they will be the beneficiaries of our dedication; second, by the merit of hearing the Buddha’s names and mantras, they can attain liberation from samsara. It does not mean that liberation can be attained in their next life, which ultimately depends on how serious their respective karmic hindrances are, but it should not take too long.

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

What is the ideal number of beings to be liberated each time? Given the right conditions, it should be as many as possible. With limited amount of money, the smaller the size of the beings, the bigger the quantity that can be bought. That means more lives can be saved and helped to attain liberation. On the other hand, liberating larger animals such as yaks and sheep or larger fish like silver carp are also meaningful. We can plainly see that these beings generally endure more pain when being killed due to their larger body. As we help them avoid this immense fear and pain, we also gather greater merit at the same time. The Abhidharma-kosha-shastra said so too. For example, which is a greater evil, killing an ant or an ox? Although they are both living beings, the dying pain of an ant is not as enormous as that of an ox, relatively speaking. Due to the large size of the body, animals like yaks and sheep suffer more physical pain when they die. It is therefore a relatively greater evil to kill large animals.

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

Someone had asked on the web about how to benefit beings that were about to be killed in a market or some other places if there was not enough money to buy their freedom. The easy way is simply to recite the Buddha’s names to them. If you happen to have some pure nectar pills, feed them those. Otherwise, just recite the Buddha’s names and mantras. The merit of reciting and hearing the Buddha’s names and mantras is beyond imagination, which undoubtedly will benefit the poor beings. 

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

How can we be endowed with wisdom when liberating living beings? Being mindful that it is a practice of Mahayana, that it can sow the virtuous seeds for the liberators and benefit the liberated, and that the recitations of sutras, mantras and the Buddha’s names are complete, all exemplify the meaning of having wisdom. The more profound understanding of that is to know the liberator, the liberated and the act of liberation are all illusory phenomena, devoid of self nature. If one were to gain thorough knowledge of such view and subsequently attain realization thereof, it would naturally signify attaining the state of supreme wisdom. But absent this view, wisdom can still be had in the manner otherwise described above.

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

Some people think that there are countless fish being sold at the markets and what they can buy is only a fraction of the total. Not even to buy out just one type of fish is possible, much less all the fish. They wonder how meaningful it is to continue liberating lives under the circumstances, and thereby become disenchanted.

The fact is that aspiring to save all the lives in the world is an impossible mission even for the Buddha who can only help those whose karma has ripened and are thus receptive to his teachings. To those with yet ripened karma, the Buddha is equally helpless. The same reasoning also applies to liberating living beings. For someone as wealthy as Indra, the ruler of gods, not even he could have bought and liberated all the beings there were. As there are an infinite number of sentient beings, it could be even beyond the Buddha’s reach sometimes to deliver beings from samsara, let alone what our limited ability can achieve. All we can do is to help other beings the best we know how.

But in addition to managing everyday life, we also need to have unshakable determination to take the path to liberation. On this basis, even one single recitation of mantra can begin to turn us around. 

- Quote from The Right View, "The Way of Living and the Meaning of Life"

It is stated in the sutras that every participant in the liberation of living beings will gather the full amount of merit thereof. For example, if one hundred people were to kill one person, this bad karma would not be divided among the hundred but borne completely by each one. The same goes for virtuous deeds. If one hundred people were to set one life free, everyone would collect the whole merit of freeing one life, not just one percent of it. Over the years, we have freed billions of lives in this part of China and all the merit accumulated thus far belongs to every participant. Just liberating living beings is already an incredibly virtuous practice. When it is conducted together with unselfish motivation and proper dedication, it will garner even more inconceivable merit which undoubtedly can purify all our negative karma.

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

Although freeing small fry or other beings that will not be killed in the near future is also liberating living beings, they are not lives saved at the point of being killed. To engender great merit and to be deemed a genuine form of fearless offering, lives saved should be those that are about to be killed such as the assorted fish sold in the marketplace.

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

The true meaning of going back to the natural state is to give up all desires for samsara and take the path leading to ultimate liberation. So the first thing we should do now is to generate renunciation.
