There are dravyamaya-yajñas. Dravyamaya-yajñas means giving in charity. That is called dravyamaya-yajña. Jñānamaya-yajña means to engage oneself into the studies of the Vedas very critically, nicely. That is called jñānamaya-yajña.
And those who are controlling the senses, that is called yogamaya-yajña. So there are different kinds of yajñas, and according to different kinds of yajñas, there are different kinds of yogis also. Each one of them is called yogi. So according to the type of yajña, there are different kinds of yogis. Just like we are. We are trying in the process of transcendental loving service, so we are bhakti-yogīs. We are called yogi in the devotional service. Of course, we'll find in the Sixth Chapter that bhakti-yogī is the topmost yogi.
- yoginām api sarveṣāṁ
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
- (BG 6.47)
And that is stated by the Lord that "There are different kinds of yogis, but the person who is always under the contemplation of Me, he is the highest yogi."
Therefore devotional service, loving devotional service of the Supreme Lord, that is the topmost kind of yogi. That is we find in everywhere, in every chapter, in every verse of this Bhagavad-gītā, that Kṛṣṇa consciousness, which we are trying to culture, that is the highest type of yoga.
- apāne juhvati prāṇaṁ
- prāṇe 'pānaṁ tathāpare
- prāṇāpāna-gatī ruddhvā
- apare niyatāhārāḥ
- prāṇān prāṇeṣu juhvati
These prāṇa, apāna... There are breathing control. There are different kinds of air passing within the body, and the yoga system, the controlling, that is also another kind of sacrifice.
- sarve 'py ete yajña-vido
- yānti brahma sanātanam
Now, what is the purpose of this sacrifice? Now, it is concluded here that sarve 'py ete yajña-vidaḥ. All these different kinds of yajña, they are meant for diminishing our sinful reaction, our sinful reaction. Because we are accumulating many sinful reaction in different births. So if we perform sacrifice, if we perform yoga, that process helps us in diminishing our accumulated, I mean to say, sinful reaction. But so far this harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21), oh, this is the easiest and the most, I mean to say, supreme process. As we have discussed many times, the Lord Caitanya recommends that ceto-darpaṇa-mārjanam (CC Antya 20.12). By this, paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam, by the performance of saṅkīrtana—
- Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa Hare Hare
- Hare Rāma Hare Rāma Rāma Rāma Hare Hare
- —immediately the dust from the mind is clear. That is recommended.
So in spite of it is very easy process, it is the supreme process. It surpasses all kinds of other yajñas and yoga systems.
- nāyaṁ loko 'sty ayajñasya
- kuto 'nyaḥ kuru-sattama
The Lord says that "Those who are not performing yajña, they cannot be happy even in this world, in this life, and what to speak of next life." This is the con... Therefore we have to perform sacrifice. Nāyaṁ lokaḥ, ayaṁ lokaḥ.
Ayam, in this world, in which we are at present, that is also becoming more miserable. At the present moment people are feeling so much painful in the modern existence because this process of yajña has been... Completely, people are engaged, "Work hard, earn money and be engaged in sense gratification." That's all. This is the whole program, at the present moment is going on. That cannot bring any peace and prosperity to the society. We have to perform yajñas. That is the natural law.
