Bhagavad Gita 15.2
Its branches shoot upwards and downwards, deriving their nourishment from the qualities; its buds are the objects of sense; and its roots, which follow the law, causing man's regeneration and degeneration, pierce downwards into the soil.
अधश्चोर्ध्वं प्रसृतास्तस्य शाखा गुणप्रवृद्धा विषयप्रवालाः।अधश्च मूलान्यनुसन्ततानि कर्मानुबन्धीनि मनुष्यलोके॥adhaścordhvaṃ prasṛtāstasya śākhā guṇapravṛddhā viṣayapravālāḥ|adhaśca mūlānyanusantatāni karmānubandhīni manuṣyaloke||
