Wealth from the forest that increases the treasuries of kings and other wealthy persons is excellent, that is, more appreciated than wealth from the countryside because it is extraordinary. Lord Rāmacandra implies, “Therefore, we who are returning to the city  [of Ayodhyā] from the forest should catch this [deer] which is an extraordinary item of wealth.”

GLOSS. Śukrācārya [once planned to procure forest essences and] constructed a well filled with them. [He then used those essences] to bring the dead [asuras] back to life.

NOTE. In Vedic culture, natural resources provided by the demigods, who are agents of the Supreme Personality of Godhead in the material world, are recognized as the most important asset for humanity. Prabhupāda explains this matter thus:

One should know […] that all the necessities of life that the human society requires are supplied by the demigod agents of the Lord. No one can manufacture anything. Take, for example, all the eatables of human society. These eatables include grains, fruits, vegetables, milk, sugar, etc., for the persons in the mode of goodness, and also eatables for the nonvegetarians, like meats, none of which can be manufactured by men. Then again, take for example heat, light, water, air, etc., which are also necessities of life—none of them can be manufactured by the human society. Without the Supreme Lord, there can be no profuse sunlight, moonlight, rainfall, breeze, etc., without which no one can live. Obviously, our life is dependent on supplies from the Lord. Even for our manufacturing enterprises, we require so many raw materials like metal, sulphur, mercury, manganese, and so many essentials—all of which are supplied by the agents of the Lord, with the purpose that we should make proper use of them to keep ourselves fit and healthy for the purpose of self-realization, leading to the ultimate goal of life, namely, liberation from  the material struggle for existence. (Bhagavad-gītā 3.12 purport)
