Verse
अधश्चोर्ध्वं प्रसृतास्तस्य शाखागुणप्रवृद्धा विषयप्रवालाः ।अधश्च मूलान्यनुसंततानिकर्मानुबन्धीनि मनुष्यलोके ॥
The branches of this cosmic tree extend both below and above (below in the material, above in the supraphysical planes), they grow by the gunas of Nature; the sensible objects are its foliage, downward here into the world of men it plunges its roots of attachment and desire with their consequences of an endlessly developing action.
