Bhagavad Gita 15.2
अधश्चोर्ध्वं प्रसृतास्तस्य शाखा गुणप्रवृद्धा विषयप्रवालाः । अधश्च मूलान्यनुसन्ततानि कर्मानुबन्धीनि मनुष्यलोके ॥
adhaś cordhvaṁ prasṛtās tasya śākhā guṇa-pravṛddhā viṣaya-pravālāḥ | adhaś ca mūlāny anusantatāni karmānubandhīni manuṣya-loke ||
Translation
Its branches spread downward and upward, nourished by the qualities, with sense-objects as twigs; and below, its roots reach down too, binding it to action in the world of men.
Reflection
Which sense-object is currently sprouting a new root I would rather not water?
Read this verse in its chapter: Chapter Fifteen
Same tree mapped in finer detail. Branches grow both ways now, because heavens and hells are still parts of one organism, not separate cosmoses. Fertilizer is the three gunas, freshly remembered from chapter fourteen. Sprouts at the tips are vishayas, the small bright sense-objects that the mind keeps reaching for. Then a second root system runs below the surface in human birth, made of karmas tying each act forward to its return visit. Picture a banyan whose visible canopy is one life, whose underground rootlets are the queued consequences. Most of us try to garden the leaves. Krishna keeps pointing at the roots.
