In the early stages of the Buddha’s spiritual research, he applied various methods to control his mind including austerities and fasting. But it was only when he adopted the right course of meditation that his eye of wisdom opened and light appeared. After this experience, says the Buddha, he remained securely on the path: By inconceivable good karmas, I have rid myself of delusions And have achieved various lights. By all kinds of [virtuous] practices, I abide securely in the Buddha’s path. (Quoted from Maharatnakuta Sutras, in A Treasury of Mhayana Sutras, tr. The Buddhist Association of United States, p. 192) The Buddha refers to the experience of light while describing a Brahmin what he experienced at the time of enlightenment: In the last watch of the night, Brahmin, I attained the third true knowledge; Ignorance is destroyed, wisdom is arisen; darkness is dispelled and light is arisen. (Majjhima Nikaya i, p. 23) Speaking of the emergence of light during the time of the Buddha’s meditation, the Lotus Sutra (Saddharmapundarika) says: His body was motionless and his mind had reached perfect tranquillity. And as soon as the Lord had entered upon his meditation, there fell a great rain of divine flowers.....And at that moment there issued a ray of light from within the point between the eyebrows (Hindus call it Shiva Netra) of the Lord. It extended over eighteen hundred thousand Buddha fields.....so that all those Buddha-field appeared wholly illuminated by its radiance. (Saddharmapundarika, 1 prose). Then, indicating the marvellous state of the Buddha’s enlightenment, marked by splendorous light and sound, the Lalitavistara says: All the universe were illuminated by a splendorous light......They became resonant, greatly resonant and resonant around, and a divine sound resounded majestically, and resounded all around. (Lalitvistara, 22 prose, tr. Shanti Bhikshu Shastri, p. 663) The Lotus sutra also gives an account of the Buddha’s enlightenment in terms of resounding music: Now, monks, while the Lord was just on the summit of the terrace of enlightenment, the gods of paradise prepared for him a magnificent royal throne....and no sooner had the Lord occupied the seat of enlightenment then the Brahmakayika gods scattered a rain of flowers all around the seat of enlightenment....and the divine drums of God sounded... and the celestial musical instruments were played ceaselessly. (Sadd 7, prose, p. 156-157) The Buddha’s enlightenment marked the turning point in his life. Having become a veritable fountain of wisdom and endowed with boundless compassion, he undertook the journey with a mission to impart the same wisdom to humanity. When he was on his way to Benaras (Varansi or Kashi) to begin rotating the wheel of Dharma – to deliver the first discourse on the Dharma for the first time – he met the ascetic named Upaka, who enquired of the Buddha about his mission. At this the Buddha replied: I shall go to Benaras, And having gone there to the city of Kashi, I shall kindle the incomparable light, For people lost in blindness. And I shall beat the drum of deathlessness For people devoid of shabd [inner sound]. ((Lalitvistara, 22 prose, tr. Shanti Bhikshu Shastri, p. 770) It is worth mentioning here tha Hindu’s Upnishads also talk of that same shabad (Anhat Naad) with divine light and sound in the inner regions. Gurbaani also talks of Shabad having light and sound in the inner regions.
