सर्वभूतेषु येनैकं भावमव्ययमीक्षते।
अविभक्तं विभक्तेषु तज्ज्ञानं विद्धि सात्त्विकम्।।18.20।।
।।18.20।। जिस ज्ञान से मनुष्य? विभक्त रूप में स्थित समस्त भूतों में एक अविभक्त और अविनाशी (अव्यय) स्वरूप को देखता है? उस ज्ञान को तुम सात्त्विक जानो।।
In varna-asrama or the divisions of society the Brahmins comprise the spiritual heiarchy, the ksatriyas the royal and warrior class, the vaisyas the farmer and mercantile class and the sudra the worker class serving the previous three. The other four divisions are brahmacari or celibate student life, grihasta or married householder life, vanaprastha or separation from wife and family and sannyasa or complete renunciation from society and exclusive devotion to the Supreme Lord Krishna or any of His authorised incarnations as revealed in Vedic scriptures. There are all variances in appearance within these eight divisions such as tall, strong, attractive, delicate, etc. Yet one who sees the one undivided, spiritual reality of the atma or immortal souls existing equally within all jivas or embodied beings and perceives that they are all inconceivably indivisible although manifesting individually sharing collectively in eternality is firmly situated in sattva guna the mode of goodness. One who sees the atma as indestructible and unchangeable within the destructible and changeable physical body and who although performing variegated prescribed activities in any capacity has comprehended that they are not the actual doer and also have no interest in the rewards of actions is situated in sattva guna.
