The easiest process is to hear.
- śravaṇaṁ kīrtanaṁ viṣṇoḥ
- smaraṇaṁ pāda-sevanam
- arcanaṁ vandanaṁ dāsyaṁ
- sakhyam ātma-nivedanam
- (SB 7.5.23)
These nine processes. So the easiest process is simply hearing. Hearing of this Bhagavad-gītā or Śrīmad-Bhāgavatam from the realized person, that will train up oneself, one, into the thoughts of the Supreme Being twenty-four hours, which will lead one ultimately, anta-kāle, to remember the Supreme Lord, and thus leaving this body, he will have a spiritual body, a spiritual body, just fit for association with the Lord.
