Srimad Bhagavatham : 6.1.49.
Slokam-49. ( As a sleeping person acts according to the body manifested in his dreams and accepts it to be himself, so one identifies with his present body, which he acquired because of his past religious or irreligious actions, and is unable to know his past or future lives.)
yathajnas tamasa yukta upaste vyaktam eva hi,
na veda purvam aparam nashta-janma-smrtis tath.

na veda = does not know;
purvam—the past body;
aparam = the next body;

A man engages in sinful activities because he does not know what he did in his past life to get his present materially conditioned body, which is subjected to the threefold miseries. As stated by Rshabhadeva in Bhaghavatham (5.5.4), : a human being who is mad after sense gratification does not hesitate to act sinfully. He performs sinful actions simply for sense gratification. This is not good, because of such sinful actions, one receives another body in which to suffer as he is suffering in his present body because of his past sinful activities.
It should be understood that a person who does not have Vedic knowledge always acts in ignorance of what he has done in the past, what he is doing at the present and how he will suffer in the future. He is completely in darkness. Therefore the Vedic injunction is, tamasi ma: “Don’t remain in darkness.” Jyotir gama: “Try to go to the light.” The light or illumination is Vedic knowledge, which one can understand when he is elevated to the mode of goodness or when he transcends the mode of goodness by engaging in devotional service to the spiritual master and the Supreme Lord.
This is described in the Svetasvatara Upanishad (6.23):
“Unto those great souls who have implicit faith in both the Lord and the spiritual master, all the imports of Vedic knowledge are automatically revealed.” Svetasvatara Upanishad (6.23)
“No one can understand Krishn as He is by the blunt material senses. But He reveals Himself to the devotees, being pleased with them for their transcendental loving service unto Him.” (Bhakti-rasamrta-sindhu 1.2.234)
“One can understand the Supreme Personality as He is only by devotional service. And when one is in full consciousness of the Supreme Lord by such devotion, he can enter into the kingdom of God.” (B-gita. 18.55)
These are Vedic instructions. One must have full faith in the words of the spiritual master and similar faith in the Supreme Personality of Godhead. Then the real knowledge of Jivatma and Paramatma and the distinction between matter and spirit will be automatically revealed. This Atma-tattva, or spiritual knowledge, will be revealed within the core of a devotee’s heart because of his having taken shelter of the lotus feet of a mahajana such as Prahlada.
According to his association with the material modes of nature—goodness, passion and ignorance—a living entity gets a particular type of body. The example of one who associates with the mode of goodness is a qualified brahma?a. Such a brahma?a knows past, present and future because he consults the Vedic literature and sees through the eyes of sastra (sastra-cak?u?). He can understand what his past life was, why be is in the present body, and how he can obtain liberation from the clutches of maya and not accept another material body. This is all possible when one is situated in the mode of goodness. Generally, however, the living entities are engrossed in the modes of passion and ignorance.
Everything depends on bhagavan, or ajah the unborn. Why doesn’t one please Bhagavan to receive a better body? The answer is ajñas tamasa: because of gross ignorance. One who is in complete darkness cannot know what his past life was or what his next life will be; he is simply interested in his present body. Even though he has a human body, a person in the mode of ignorance and interested only in his present body is like an animal, for an animal, being covered by ignorance, thinks that the ultimate goal of life and happiness is to eat as much as possible. A human being must be educated to understand his past life and how he can endeavor for a better life in the future. One who is interested only in his present body and who tries to enjoy his senses to the fullest extent is understood to be engrossed in the mode of ignorance. His future is very, very dark. Indeed, the future is always dark for one who is grossly covered by ignorance. Especially in this age, human society is covered by the mode of ignorance, and therefore everyone thinks his present body to be everything, without consideration of the past or future.
