Śrīmad-Bhāgavatam
[Canto 5, Ch. 14]
Krṣṇa consciousness movement is trying to bring intelligent human beings to the platform of devotional service. Instead of wasting time trying to attain a better position in material life, one should simply endeavor to return home, back to Godhead. Then all problems will be solved. As stated in  Śrīmad-Bhāgavatam  (1.2.17):
śrṇvatāṁ sva-kathāḥ krṣṇaḥ 
  puṇya-śravaṇa-kīrtanaḥ 
  hṛdy antaḥ-stho hy abhadrāṇi 
  vidhunoti su-hṛt-satām
“Śrī Krṣṇa, the Personality of Godhead, who is the Paramātmā [Supersoul] in everyone’s heart and the benefactor of the truthful devotee, cleanses the desire for material enjoyment from the heart of the devotee who relishes His messages, which are in themselves virtuous when properly heard and chanted.”
One simply has to follow the regulative principles, act like a  brāhmaṇa , chant the Hare Krṣṇa  mantra  and read  Bhagavad-gītā  and  Śrīmad-Bhāgavatam . In this way one purifies himself of the baser material modes ( tamo-guṇa  and  rajo-guṇa ) and, becoming freed from the greed of these modes, can attain complete peace of mind. In this way one can understand the Supreme Personality of Godhead and one’s relationship with Him and thus be promoted to the highest perfection ( siddhiṁ paramāṁ gatāḥ ).
