The Lord then informed Sanatane Gosvami that He had previously instructed his younger brother, Roupa Gosvami, in Prayag (Allahabad, city of India). He assured Sanatane that He had bestowed full powers on Roupa to spread the knowledge He had given him. Chaitanya then ordered Sanatane to write works on the service of spiritual love of the Lord, and authorized him to rediscover the various sites of the entertainment of Krishna in the area of Mathura. He also advised him to build temples in Vrindavane and to write books on the principles of Vaisnavism, the action initiated by the transcendentals of the highest order, who express love and devotion to Lord Krishna, and thus take pleasure in spreading the knowledge of his Divine Person and his teaching for the greater good of human beings.
Lord Chaitanya also taught him how to experience an integral relationship with Krishna in the material universe as well as the futility of arid renunciation. Let us understand here that in the present age, many are those who adopt the order of renunciation without having reached a high degree of spiritual consciousness. Lord Chaitanya did not approve of adopting the path of renunciation without having a perfect knowledge of Krishna consciousness. We find in fact that the activities of many so-called renouncing or hermits, turn out to be lower than those of ordinary people, while they claim to belong to the order of renunciation. Chaitanya Mahaprabhu did not accept such hypocrisy. Also he asked Sanatane Gosvami to write in an elaborate way on the question in his various works.
Spiritual perfection, which can be experienced even in the material universe, is described in the Bhagavad-Gita, Words of Krishna, Christ, God, the Supreme Person, by Lord Krishna, when He says:
The devotee, envious of nothing, who behaves with everyone as a benevolent friend, who does not believe himself to be the possessor of anything, who is freed from the false ego and remains the same in joy as in sorrow, who forgives, who always knows the contentedly and resolutely engaged in devotional service, and whose mind and body are surrendered to the Supreme Lord, he is very dear to Me.
The devotee who never causes agitation for others and whom joys and sorrows do not affect, who does not depend in any way on the modes of material action; the pure being, expert in everything, free from all anxiety, free from suffering, and who does not seek the fruit of his acts, this one is very dear to Me.
He who takes neither joy nor sorrow, who neither grieves nor covets, who renounces the favorable as well as the unfavorable, this one is very dear to Me.
He who shows himself equal to friend or foe, who remains the same in glory or reproach, heat or cold, praise or blame, forever clean from all filth, always silent, satisfied of everything, heedless of lodging, and who, established in knowledge, serves Me with love and devotion, this one is very dear to Me.
Whoever, full of faith, in this imperishable way of devotional service is fully committed, making Me the supreme goal, this is very dear to Me.
