Sa sannyāsī ca yogī ca na niragnir na cākriyaḥ. Na niragniḥ. Niragniḥ means "those who have left home." In the varṇāśrama-dharma, one who is a householder, he has to perform daily yajña. So there is fire. Fire. Still we find in the Parsis, they are fire worshiper. So this fire worship is recommended in Vedic literature. So gṛhasthas, or the householders, they are expected to offer, I mean to say, sacrifice in the fire daily.
- yaṁ sannyāsam iti prāhur
- yogaṁ taṁ viddhi pāṇḍava
- na hy asannyasta-saṅkalpo
- yogī bhavati kaścana
- (BG 6.2)
Now, here is very important point. Yaṁ sannyāsam iti prāhuḥ. Lord Śrī Kṛṣṇa instructs Arjuna that "Whatever is known as sannyāsa, renounced order of life, that is also yoga." Yoga system and sannyāsa, is there is no difference, because everything on the yoga system . . . this Bhagavad-gītā is also known as yoga system. You'll find here three kinds of yoga: karma-yoga, jñāna-yoga and bhakti-yoga.
So just like you have got a staircase to rise up to the fifth or sixth or tenth floor, or . . . er, or more than that, the whole staircase or the lift service is called yoga. Now, somebody may be in the fifth floor, somebody may be in the tenth floor, somebody may be on the fiftieth floor, but the same lift service is going. You take the lift service as the yoga, connection between the highest story to the down.
Anyone who has elevated himself to a certain platform . . . someone is called karma-yogī, someone is called jñāna-yogī, someone is called dhyāna-yogī, someone is called bhakti-yogī. So there are different kinds of yoga in this conception. Otherwise, this, this lift service, yoga service, is the same. It is, the difference is between the elevation point.
