The Vajra Prajna Paramita Sutra, p134-135When Śākyamuni Buddha first resolved to cultivate the Way, he was a master potter named Expansive Splendor. At that time there was a Buddha in the world named Sakya Tathagata who saw that conditions were ripe to take across the master potter. When the potter Expansive Splendor saw that Sakya Tathagata had come, he welcomed him eagerly. It was with extreme pleasure that he said, “Ahh, I too see the Buddha.” He gazed at the Buddha and then asked him to speak dharma. Upon hearing the dharma the potter immediately made the vow: “Buddha, you are truly superb. In the future when I realize Buddhahood, I will be a Buddha just like you. My name will also be Śākyamuni.” He made the vow to cultivate the Way before that Buddha. Seventy-five thousand Buddhas appeared in the world after that Sakya Buddha, the last of whom was Accumulation of Jewels Tathagata. The period of these 75,000 Buddhas is called the first asaṃkhyeya kalpa. The actual length of time in that first asaṃkhyeya kalpa is certainly incalculable. From Accumulation of Jewels Tathagata to Burning Lamp Buddha is a period in which 76,000 Buddhas appeared in the world, and is called the second asaṃkhyeya kalpa. From Burning Lamp Buddha to Victorious Contemplation Buddha is a period in which 77,000 Buddhas appeared in the world and is called the third great asaṃkhyeya kalpa. It was during those three great asaṃkhyeya kalpas that Śākyamuni Buddha cultivated the Way to the realization of Buddhahood.
Therefore the Buddha said, “Prior to Burning Lamp Buddha, I encountered eighty-four thousands of millions of billions of nayutas of Buddhas, and made offerings to them all, and served them all without exception.” Throughout his long period of cultivation Śākyamuni Buddha never failed to serve the Buddhas who appeared in the world. He made offerings to them all.
However the Buddha further pointed out that “If there is someone in the Dharma Ending Age who can receive the sūtra with his mind and hold it with his body, and who can read or recite it, his merit and virtue is greater than mine for having made offerings for three great asaṃkhyeya kalpas to all eighty-four thousands of millions of nayutas of Buddhas, by several hundred, thousand, million, billion times. Neither calculation, nor analogy, nor comparison can adequately express it.
