Prabhupāda: Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (B.G.10:10). When Kṛṣṇa sees that "He is worshiping Me with faith and reverence and love," then buddhi-yogam dadāmi tam. He'll give you intelligence. He is within you. Therefore I was saying, "First of all become fit. First of all deserve. Then desire." Why foolishly you desire something for which you do not deserve? That is your fault. That is misuse. Don't desire something without being deserving. So these are the process given how to think, how to meditate upon Kṛṣṇa. So practice it. Become qualified. Then you'll see everything.

So Kṛṣṇa is teaching in this Fourth Chapter how to work. Yadṛcchā-lābha. Don't be greedy, so "This man is millionaire, so I have to become a millionaire." Competition. That is material disease. Now there is competition in between the capitalist and the communist. Now the communist or the laborer class men, they are thinking that "Why the capitalist should gain? We must gain. The industry is being conducted by us. The profits shall be divided between us. Why to the capitalist?" So that is not the solution. That is from frying pan to the fire. Either the world is run on the principle of communistic philosophy or capitalistic philosophy, it will never be happy. Here is the formula, that everyone should be satisfied with the profit that he can easily make. That's all. Yadṛcchā-lābha. Not that everyone will have the same profit.
(Lecture on Bhagavad-Gita--4:22--Bombay--11th. April, 1974).

A devotee should not be proud of his acquisitions. The symptoms of a devotee are meekness and humility. Although spiritually very advanced, he will always remain meek and humble, as Kavirāja Gosvāmī and all the other Vaiṣṇavas have taught us by personal example. Caitanya Mahāprabhu taught that one should be humbler than the grass on the street and more tolerant than the tree. One should not be proud or falsely puffed up. In this way one will surely advance in spiritual life.
(Srimad bhagavatam--3:29:18).
