ऊर्ध्वमूलमधःशाखमश्वत्थं प्राहुरव्ययम्।
छन्दांसि यस्य पर्णानि यस्तं वेद स वेदवित्।।१५.१।।

Lord Shri Krishna continued: This phenomenal creation, which is both ephemeral and eternal, is like a tree, with its seed above in the Highest and its ramifications below on this earth. The scriptures are its leaves, and he who understands this knows.

Hindi Meaning

श्रीभगवान् बोले -- ऊपरकी ओर मूलवाले तथा नीचेकी ओर शाखावाले जिस संसाररूप अश्वत्थवृक्षको अव्यय कहते हैं और वेद जिसके पत्ते हैं, उस संसारवृक्षको जो जानता है, वह सम्पूर्ण वेदोंको जाननेवाला है।
