In the vedic scriptures you can find answers that are good to know. Where do we come from? Clear statement we can find also in the purports of the mantras 16. and 17. of the Śrī Īśopaniṣad given bei A.C. Bhaktivedanta Swami. That is a standard book and all Vaishnavas and truth-seeker should have read it and accept the philosophical points.
(from mantra 16.)
The all-pervading feature of the Lord – which exists in all circumstances of waking and sleeping as well as in potential states and from which the jīva-śakti (living force) is generated as both conditioned and liberated souls – is known as Brahman.
(from mantra 17.)
As we have learned from previous mantras, the brahma-jyotir emanating from the transcendental body of the Lord is full of spiritual sparks that are individual entities with the full sense of existence. Sometimes these living entities want to enjoy their senses, and therefore they are placed in the material world to become false lords under the dictation of the senses. The desire for lordship is the material disease of the living being, for under the spell of sense enjoyment he transmigrates through the various bodies manifested in the material world.

So if I am a conditioned soul?
Śrīla Bhaktivinoda Ṭhākura explains these verses (of Śrī Īśopaniṣad) in this way:
“One should regard a devotee of Krishna to be on the right path of the saints, even though such a devotee may seem to be su-durācāra, ‘a person of loose character.’ One should try to understand the real purport of the word su-durācāra. A conditioned soul has to act for double functions – namely for the maintenance of the body and again for self-realization. Social status, mental development, cleanliness, austerity, nourishment and the struggle for existence are all for the maintenance of the body.
The self-realization part of one’s activities is executed in one’s occupation as a devotee of the Lord, and one performs actions in that connection also. One must perform these two different functions along parallel lines, because a conditioned soul cannot give up the maintenance of his body.
The proportion of activities for maintenance of the body decreases, however, in proportion to the increase in devotional service. As long as the proportion of devotional service does not come to the right point, there is a chance for an occasional exhibition of worldliness. But it should be noted that such worldliness cannot continue for long because, by the grace of the Lord, such imperfections will come to an end very shortly. Therefore the path of devotional service is the only right path. If one is on the right path, even an occasional occurrence of worldliness does not hamper one in the advancement of self-realization.”
