The Supreme Personality of Godhead said: It is said that there is an imperishable banyan tree that has its roots upward and its branches down and whose leaves are the Vedic hymns. One who knows this tree is the knower of the Vedas.

Just see how Lord Krishna is using those above examples from  nature to help drive home some important philosophical points in descriptions of the Vedas . Frequently, the Srimad Bhagavatam  uses nature  to illustrate key lessons to be learned.

The Vedas is extremely broad , it can be applied  in different ways at all times in all places with the variety of persons in societies. Whatever their status or current conditioning, they all can all find the benefits

Ultimately, the pure sounds of the Vedas are revealed within the heart of someone who is sincere and who is 24 hours exclusively engaged in the services of Divinity , there are no deviations in the hearts of the pure representatives , thus Krishna or God is in relationship with such persons.
