nāyaḿ loko ’sty ayajñasya
kuto ’nyaḥ kuru-sattama

Translation of Bhagavad Gita 4.31

O best of the Kuru dynasty, without sacrifice one can never live happily on this planet or in this life: what then of the next?

Commentary by Sri A.C. Bhaktivedanta Swami Prabhupada of Gaudiya Sampradaya:

Whatever form of material existence one is in, one is invariably ignorant of his real situation. In other words, existence in the material world is due to the multiple reactions to our sinful lives. Ignorance is the cause of sinful life, and sinful life is the cause of one’s dragging on in material existence. The human form of life is the only loophole by which one may get out of this entanglement. The Vedas, therefore, give us a chance for escape by pointing out the paths of religion, economic comfort, regulated sense gratification and, at last, the means to get out of the miserable condition entirely. The path of religion, or the different kinds of sacrifice recommended above, automatically solves our economic problems. By performance of yajna we can have enough food, enough milk, etc.—even if there is a so-called increase of population. When the body is fully supplied, naturally the next stage is to satisfy the senses. The Vedas prescribe, therefore, sacred marriage for regulated sense gratification. Thereby one is gradually elevated to the platform of release from material bondage, and the highest perfection of liberated life is to associate with the Supreme Lord. Perfection is achieved by performance of yajna (sacrifice), as described above. Now, if a person is not inclined to perform yajna according to the Vedas, how can he expect a happy life even in this body, and what to speak of another body on another planet? There are different grades of material comforts in different heavenly planets, and in all cases there is immense happiness for persons engaged in different kinds of yajna. But the highest kind of happiness that a man can achieve is to be promoted to the spiritual planets by practice of Krishna consciousness. A life of Krishna consciousness is therefore the solution to all the problems of material existence.

Commentary by Sri Vishvanatha Chakravarthi Thakur of Gaudiya Sampradaya:

The results of not acting in this way are described in this verse. One who does not perform yajna does not attain the little happiness available on this planet, what to speak of attaining the planet of the devatas.

Commentary by Sri Ramanuja of Sri Sampradaya:

4.31 He ‘who offers no sacrifices,’ i.e., he who does not devote himself to obligatory and occasional actions, preceded by the performance of the ‘great sacrifices’ etc., will not be able to achieve human ends which are associated with the material world and are called by the names of virtue, wealth and worldly satisfactions. How then can the man’s supreme end called release (Moksa), which is other than these, be attained? As Moksa, man’s supreme end, has been mentioned, other objectives different from it, are named ‘this world.’ That is, indeed, the material world. [Perhaps the idea is that all types of sacrificers should perform the Panca-Maha-Yajnas, and take the remnants of it as their daily food. Only in this way can we give some meaning to ‘ambrosial food’ connected with the performance of all the various kinds of sacrifice mentioned in the above verses.]

Commentary by Sri Sridhara Swami of Rudra Sampradaya:

Having performed yagna or offerings of worship that are not prohibited by the Vedic scriptures and after duly propitiating the Supreme Lord. Those who partake of the sanctified food remnants that is leftover which is ambrosial nectar they become spiritualised and attain by wisdom realisation of the eternal Brahman or the spiritual substratum pervading all existence. But for those who ignore or neglect to perform yagna their defect is being pointed out that in this material world which is full of the three fold miseries of old age disease and death there will be no chance of happiness for them. So there is no need for such offenders to even think for enjoyment in the heavenly spheres. Lord Krishna is indirectly stating that for one’s ultimate well being one must perform yagna as a way of life without reservation.

Commentary by Sri Madhvacharya of Brahma Sampradaya:

By diminishing the intake of food the influence of the senses are greatly reduced due to weakness of body. The speech is also so diminished as well. Knowing that the senses and tongue which governs both eating and speaking are all subservient to the mind as revealed in the Vedic scriptures, one of controlled mind should only eat what has been ordained and sanctified in yagna or offerings of worship to the Supreme Lord according to the injunctions of the Vedic scriptures otherwise there is no hope for redemption in this world or the next.

Now begins the summation.

Due to yagna and propitiation to the Supreme Lord are the restraint of the senses achieved. By considering that such efforts are the sole purpose of existence one should wholeheartedly engage in yagna without reservation. One should consider one’s life as the oblation offered to the Supreme Lord in full surrender following the injunctions recommended in the Vedic scriptures. In the Brahma Vaivartaka Purana it states that one should realise the Supreme Lord as the yagna and propitiate Him with body, mind and words. When the Brahman or the spiritual substratum pervading all existence has been perceived then the relation between the performer, the activity performed, the recepient of the performance and the result of the performance are all factually not separate from the Supreme Lord one will then experience the actual presence of the Supreme Lord everywhere in all situations.

Commentary by Sri Keshava Kashmiri of Kumara Sampradaya:

Commentary by Sri Adi Shankaracharya of Advaita Sampradaya:

4.31 Yajna-sista-amrta-bhujah, those who partake of the nectar left over after a sacrifice, i.e. those who, after performing the sacrifices described above, eat, during the leisure after the sacrifice, the food called nectar, as prescribed by the injunctions; yanti, reach; sanatanam brahma, the eternal Brahman. For the sake of consistency (with the Upanisads) it is understood that if they (the sacrificers) are seekers of liberation, (then they reach Brahman) in due course of time. [The Upanisads describe the different stages through which those who do good deeds and practise meditation have to pass before reaching the qualified Brahman after death. For liberation there is need also of purification of the heart, Thus, they reach Brahman by stages, and not immediately after death. (See Ch. 8.5 and subsequent portion; also, Br. 4.3.35 to 4.4.25, etc.)] Even ayam lokah, this world, common to all beings; na asti, ceases to exist; ayajnasya, for one who does not perform sacrifices, for him who does not have to his credit even a single one of the above sacrifices. Kutah anyah, what to speak of the other world which can be achieved through special disciplines; kurusattama, O best among the Kurus!

Commentary by Sri Abhinavagupta of Kaula Tantra Sampradaya:

4.31 Yajna-etc. They enjoy the nectar of the Parananda and the Nirananda, which is of the nature of relaxing in their own Self and which has been ordained-i.e., brought about – by the sacrifice and which is the remnant of the sacrifice in the form of satisfying [the deities of] their own sense-organs. Yet, remaining as Brahman Itself, they get themselves mixed [in this mundane life] to their heart-content. Here we refrain [ourselves] from the free talk of clearly disclosing what is highly secret. Further, here a good amount of tasty secret has been kept well hidden. Yet, this becomes an object of [actual] chewing and [thus] becomes the cause for enjoying (realising) what is Real, in the case of those persons whose [bodily and internal] elements have been equalised by the powerful medicines of the tradition learnt from the revered teachers, pleased with service, laden with very assiduous devotion. In this context other explanations have been offered by [other] commentators. However, let the intellectuals weigh and decide for themselves, those explanations and the etymological interpretations offered by our revered preceptors. So, look ! What is the use of the sport of criticising the statements of those commentators ? Hence let us stick to only what we have begun with.
