Those who are acting, those who are situated on the platform of goodness, they are promoting their existential status in higher planets. Ūrdhvaṁ gacchanti sattva-sthā madhye tiṣṭhanti rājasaḥ (BG 14.18):
And those who are in the modes of passion, they will remain here. And jaghanya-guṇa-vṛtti-sthā adho gacchanti tāmasāḥ: and those who are very addicted to all abominable habits, they are clearing their way to hellish life. So to abominable life is these four principles. That we are trying to avoid.
So Lord Caitanya's teaching, the sum and substance of His teaching, is to understand that we are eternal servant of God, and if we immediately engage our energy to satisfy Kṛṣṇa, then immediately we are transferred to the spiritual platform. And if we stick to that activities on the spiritual platform, then, as assured by Lord Kṛṣṇa, then, after leaving this body, we go back to Kṛṣṇa, Vṛndāvana, go back to Godhead, back to home. That is our peaceful . . . eternal, peaceful life. We should endeavor for that.
