Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Having accepted strict vows, some become enlightened by sacriﬁcing their possessions, and others by performing severe austerities, by practicing the yoga of eightfold mysticism, or by studying the Vedas to advance in transcendental knowledge.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
These sacriﬁces may be ﬁtted into various divisions. There are persons who are sacriﬁcing their possessions in the form of various kinds of charities. In India, the rich mercantile community or princely orders open various kinds of charitable institutions like dharma-sala, anna-ksetra, atithi-sala, anathalaya and vidya-pitha. In other countries, too, there are many hospitals, old age homes and similar charitable foundations meant for distributing food, education and medical treatment free to the poor. All these charitable activities are called dravyamaya-yajna. There are others who, for higher elevation in life or for promotion to higher planets within the universe, voluntarily accept many kinds of austerities such as candrayana and caturmasya. These processes entail severe vows for conducting life under certain rigid rules. For example, under the caturmasya vow the candidate does not shave for four months during the year (July to October), he does not eat certain foods, does not eat twice in a day or does not leave home. Such sacriﬁce of the comforts of life is called tapomaya-yajna. There are still others who engage themselves in different kinds of mystic yogas like the Patanjali system (for merging into the existence of the Absolute), or hatha-yoga or astanga-yoga (for particular perfections). And some travel to all the sanctiﬁed places of pilgrimage. All these practices are called yoga-yajna, sacriﬁce for a certain type of perfection in the material world. There are others who engage themselves in the studies of different Vedic literatures, speciﬁcally the Upanisads and Vedanta-sutras, or the Sankhya philosophy. All of these are called svadhyaya-yajna, or engagement in the sacriﬁce of studies. All these yogis are faithfully engaged in different types of sacriﬁce and are seeking a higher status of life. Krishna consciousness, however, is different from these because it is the direct service of the Supreme Lord. Krishna consciousness cannot be attained by any one of the above-mentioned types of sacriﬁce but can be attained only by the mercy of the Lord and His bona ﬁde devotees. Therefore, Krishna consciousness is transcendental.
