SB 3.28.36

Forgetfulness of one's relationship with the Supreme Personality of Godhead is a product of ignorance. By yoga practice, one has to eradicate this ignorance. The ignorance is that one thinks himself independent of the Supreme Lord. His relationship is eternally of love. The living entity is eternally meant for rendering transcendental loving service to the Lord. When he forgets that sweet relationship, that is called ignorance; and in ignorance, he thinks himself as the enjoyer impelled by the three material modes of nature. So when his mind is purified and he understands that the..., his mind has to be engaged and dovetailed in the desire of the Supreme Personality of Godhead, that is the perfectional stage, transcendental stage, beyond the perception of material distress and happiness.

So long he acts in his own account, he becomes subjected to all material perception of so-called happiness and distress. Actually there is no happiness. As…, as a madman whatever he does there is no happiness at all, similarly the material activities, the mental concoction that this is happiness, this is distress, actually everything is full of distress. And when such mind is dovetailed to execute according to the desire of the Lord, that is the transcendental stage. Desire to lord it over the material nature is the cause of ignorance. And so when such desire as to lord it over the material nature is completely extinguished and the desires become dovetailed in the Supreme Lord, that is the perfectional stage. This perfectional stage is described here: upalabdha-paratma-kasthaḥ (u-p-a-l-a-b-d-h-a p-a-r-a-m-t-a k-a-s-t-h-a-h). Upalabdha means realization.

As soon as we speak of realization, the…, there is indication of individuality. Without individuality there is no question of realization. In the perfectional stage, or in liberated stage, there is realization. That means the living entity keeps his individuality. Only the oneness means that he realizes happiness with the happiness of the Supreme Lord, and in the Supreme Lord there is nothing but happiness. Anandamayo 'bhyasat [Vedanta-sūtra 1.1.12]: the Lord is by nature full of transcendental happiness. So therefore in the liberated stage, oneness with the Supreme Lord means he has no other realization than happiness. But the realization is there, otherwise this word upalabdha (u-p-a-l-a-b-d-h-a) should not have been used. This upalabdha means individual realization of the transcendental happiness.
