begin where Krishna ended in Gita

 
Lord Caitanya does not give the information about the spirit soul that is already described in Bhagavad-gītā. Rather, He begins from the point where Kṛṣṇa ended His instruction.
The necessity of approaching a spiritual master is not a fashion, but is for him who is seriously conscious of the material miseries and who wants to get out of them; it is the duty of such a person to approach the spiritual master. We find similar circumstances in the Bhagavad-gita. When Arjuna was perplexed by so many problems, whether to fight or not to fight, he accepted Lord Krishna as his spiritual master. There also it was a case of the Supreme Spiritual Master instructing Arjuna about the constitutional position of the individual entity. In the Bhagavad-gita we are informed that the constitutional position of the individual entity is spirit soul; he is not matter, therefore as a spirit soul he is part and parcel of the Supreme Soul, Absolute Truth, Personality of Godhead. We also learn that it is the duty of the spirit soul to surrender, for only then can he be happy. The last instruction of the Bhagavad-gita is that the spirit soul is to surrender completely unto the Supreme Soul, Krishna, and in that way realize happiness. Here also, Lord Chaitanya in answering the questions of Sanatan is repeating the same truth, but without giving him information of the spirit soul which is described in the Gita. He begins from the point where Krishna ended his instruction. It is calculated by great devotees that Lord Chaitanya is Krishna Himself. And as He ended His instruction in the Gita, from that point he begins His instruction again, to Sanatan. The Lord said to Sanatan, "Your constitutional position is that you are pure living soul. This material body is not the identity of your real self, neither is your mind your real identity, nor your intelligence, nor is false ego the real identity for self. Your identity is that you are eternal servitor of the Supreme Lord, Krishna. Your position is that you are transcendental. Superior energy of Krishna is spiritual in constitution, and inferior external energy is material. In other words, you are between the material energy and the spiritual energy, therefore your position is marginal. In other words, you belong to the marginal potency of Krishna. You are simultaneously one with and different from Krishna because in a sense you are spirit, therefore you are not different from Krishna; but because you are only a minute particle of Krishna, you are therefore different from Krishna."    (More...)
