BG Preface and Introduction

BG Preface:

Our only purpose is to present this Bhagavad-gītā As It Is in order to guide the conditioned student to the same purpose for which Kṛṣṇa descends to this planet once in a day of Brahmā, or every 8,600,000,000 years. This purpose is stated in Bhagavad-gītā, and we have to accept it as it is; otherwise there is no point in trying to understand the Bhagavad-gītā and its speaker, Lord Kṛṣṇa. Lord Kṛṣṇa first spoke Bhagavad-gītā to the sun-god some hundreds of millions of years ago. We have to accept this fact and thus understand the historical significance of Bhagavad-gītā, without misinterpretation, on the authority of Kṛṣṇa. To interpret Bhagavad-gītā without any reference to the will of Kṛṣṇa is the greatest offense. In order to save oneself from this offense, one has to understand the Lord as the Supreme Personality of Godhead, as He was directly understood by Arjuna, Lord Kṛṣṇa's first disciple. Such understanding of Bhagavad-gītā is really profitable and authorized for the welfare of human society in fulfilling the mission of life.

SB Canto 3

SB 3.2.7, Purport:

As the sun appears in the morning and gradually rises to the meridian and then again sets in one hemisphere while simultaneously rising in the other, so Lord Kṛṣṇa's disappearance in one universe and the beginning of His different pastimes in another take place simultaneously. As soon as one pastime is finished here, it is manifested in another universe. And thus His nitya-līlā, or eternal pastimes, are going on without ending. As the sunrise takes place once in twenty-four hours, similarly the pastimes of Lord Kṛṣṇa take place in a universe once in a daytime of Brahmā, the account of which is given in the Bhagavad-gītā as 4,300,000,000 solar years. But wherever the Lord is present, all His different pastimes as described in the revealed scriptures take place at regular intervals.

SB Canto 10.1 to 10.13

SB 10.5.13, Purport:

The Lord says in Bhagavad-gītā (4.7):

yadā yadā hi dharmasya

glānir bhavati bhārata

abhyutthānam adharmasya

tadātmānaṁ sṛjāmy aham

"Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion—at that time I descend Myself." Whenever Kṛṣṇa comes, once in a day of Brahmā, He comes to the house of Nanda Mahārāja in Vṛndāvana. Kṛṣṇa is the master of all creation (sarva-loka-maheśvaram (BG 5.29)). Therefore, not only in the neighborhood of Nanda Mahārāja's estate, but all over the universe—and in all the other universes—musical sounds celebrated the auspicious arrival of the Lord.

CC Adi-lila

CC Adi 3.10, Purport:

Now is the term of Vaivasvata Manu, during which Lord Caitanya appears. First Lord Kṛṣṇa appears at the close of the Dvāpara-yuga of the twenty-eighth divya-yuga, and then Lord Caitanya appears in the Kali-yuga of the same divya-yuga. Lord Kṛṣṇa and Lord Caitanya appear once in each day of Brahmā, or once in fourteen manv-antaras, each of seventy-one divya-yugas in duration.

From the beginning of Brahmā’s day of 4,320,000,000 years, six Manus appear and disappear before Lord Kṛṣṇa appears. Thus 1,975,320,000 years of the day of Brahmā elapse before the appearance of Lord Kṛṣṇa. This is an astronomical calculation according to solar years.

Renunciation Through Wisdom

Renunciation Through Wisdom 4.5:

The undifferentiated Absolute Truth, the original Supreme Personality, Lord Śrī Kṛṣṇa, incarnates in this material world once in every day of Lord Brahmā—that is once every 8,640,000,000 solar years—to shower His mercy upon both His surrendered devotees and the atheistic nondevotees. He protects His devotees and slays the atheistic demons, thus giving the latter troublesome release, so to speak, in impersonal liberation. The Bhagavad-gītā, on the other hand, teaches liberation through devotional service to the Supreme Lord. The only way to obtain this devotional service is to take full shelter of the spiritual authority, the guru, who is coming in the line of a proper disciplic succession. Those who toil without worshiping the spiritual master will find that all their endeavors are futile.
