BG 14.6

14.6 तत्र of these? सत्त्वम् purity? निर्मलत्वात् from its stainlessness? प्रकाशकम् luminous? अनामयम् healthy? सुखसङ्गेन by attachment to happiness? बध्नाति binds? ज्ञानसङ्गेन by attachment to knowledge? च and? अनग O sinless one.Commentary Sattva is stainless like the crystal. It lays for one the trap of happiness and knowledge. It is a golden fetter. A Sattvic man compares himself with others and rejoices in his excellence. He is puffed up with his knowledge. His heart is filled with pride when he thinks that he,has more comforts or more pleasant experiences. He thinks? I am happy I am wise? and so he is bound as it were. These ideas really belong to the field but they are transferred through superimposition to the Self on account of the force of SattvaGuna.Rajas and Tamas are pitfalls on the path of knowledge.This attachment to happiness is an illusion. This is ignorance. An attribute of the object cannot belong to the subject. All the alities from desire to firmness (Cf.XIII.6) belong to the field. From ignorance? nondiscrimination is born and so the individual self is not able to discriminate between the permanent and the impermanent? the subject and the object.Knowledge is an attribute of the Antahkarana (inner instrument? viz.? mind? intellect? the unconscious and the ego) but not of the Self. It if were an attribute of the Self? it could not produce attachment and bondage. Sattva binds the soul to knowledge through attachment.

The living entities conditioned by material nature are of various types. One is happy, another is very active, and another is helpless. All these types of psychological manifestations are causes of the entities’ conditioned status in nature. How they are differently conditioned is explained in this section of Bhagavad-gītā . The mode of goodness is first considered. The effect of developing the mode of goodness in the material world is that one becomes wiser than those otherwise conditioned. A man in the mode of goodness is not so much affected by material miseries, and he has a sense of advancement in material knowledge. The representative type is the brāhmaṇa, who is supposed to be situated in the mode of goodness. This sense of happiness is due to understanding that, in the mode of goodness, one is more or less free from sinful reactions. Actually, in the Vedic literature it is said that the mode of goodness means greater knowledge and a greater sense of happiness. The difficulty here is that when a living entity is situated in the mode of goodness he becomes conditioned to feel that he is advanced in knowledge and is better than others. In this way he becomes conditioned. The best examples are the scientist and the philosopher. Each is very proud of his knowledge, and because they generally improve their living conditions, they feel a sort of material happiness. This sense of advanced happiness in conditioned life makes them bound by the mode of goodness of material nature. As such, they are attracted toward working in the mode of goodness, and, as long as they have an attraction for working in that way, they have to take some type of body in the modes of nature. Thus there is no likelihood of liberation, or of being transferred to the spiritual world. Repeatedly one may become a philosopher, a scientist or a poet, and repeatedly become entangled in the same disadvantages of birth and death. But, due to the illusion of the material energy, one thinks that that sort of life is pleasant.
