Bhagavad Gita · Chapter 13: The Field and the Knower of the Field
Bhagavad Gita 13.6
इच्छा द्वेषः सुखं दुःखं सङ्घातश्चेतनाधृतिः ।
एतत्क्षेत्रं समासेन सविकारमुदाहृतम् ॥
icchā dveṣaḥ sukhaṃ duḥkhaṃ saṅghātaścetanādhṛtiḥ | etatkṣetraṃ samāsena savikāramudāhṛtam ||
desire, aversion, pleasure, pain, the body as a whole, consciousness, and steadfastness: this, in brief, is the field together with its modifications.
Modern context
The list continues: desire, aversion, pleasure, pain, the body, even consciousness in its everyday sense and steadfastness. All of these belong to the field. Our deepest feelings, our wants and fears, our joys and sorrows, are things that happen in us, not what we fundamentally are. This is freeing. A person who knows 'I am not my anger' can watch anger arise and pass without being swept away.
