BG Preface and Introduction

BG Introduction:

Just as materialists engage their minds in reading newspapers, magazines and so many materialistic literatures, we must transfer our reading to these literatures which are given to us by Vyāsadeva; in that way it will be possible for us to remember the Supreme Lord at the time of death. That is the only way suggested by the Lord, and He guarantees the result: "There is no doubt."

"Therefore, Arjuna, you should always think of Me in the form of Kṛṣṇa and at the same time continue your prescribed duty of fighting. With your activities dedicated to Me and your mind and intelligence fixed on Me, you will attain Me without doubt." (BG 8.7)

BG Chapters 1 - 6

BG 6.10, Purport:

One should always think of Kṛṣṇa and not forget Him even for a moment. Concentration of the mind on the Supreme is called samādhi, or trance. In order to concentrate the mind, one should always remain in seclusion and avoid disturbance by external objects. He should be very careful to accept favorable and reject unfavorable conditions that affect his realization. And, in perfect determination, he should not hanker after unnecessary material things that entangle him by feelings of possessiveness.

BG Chapters 7 - 12

BG 8.7, Translation:
