The full moon day in the Hindu month of Ashad is observed as the auspicious day of Guru Poornima, a day sacred to the memory of the great sage Vyasa. All Hindus are indebted to this ancient saint who edited the four Vedas, wrote the 18 Puranas, the Mahabharata and the Srimad Bhagavata. And it says that Vyasa even taught Dattatreya, who is regarded as the Guru of Gurus.
Moon is the presiding deity of the mind.Poornima refers to Full-Moon day and it symbolizes the mind filled with happiness. Thus there is close association between the moon and mind. Evidently Guru-Poornima does not mean worshipping the Guru with some offerings alone. Guru Poornima is an occasion for clearing impure mind and keeping. Guru in the thoughts all-over without an awe of worldly desires, so that, GURU dwells in it and helps the being to come out of darkness of ignorance.
Kabir said that GURU is washer man; His disciple the cloth, soap is the creator, washed on the stone of knowledge which elicits utmost brightness.
Hindus attach paramount importance to spiritual gurus. Gurus are often equated with God and always regarded as a link between the individual and the Immortal. Just as the moon shines by reflecting the light of the sun, and glorifies it, all disciples can dazzle like the moon by gaining from their Gurus. Then, the heart of the devotee purely dwells in almighty pleasures and consciousness.
It has been said that obstructions that may be faced in the path of Spirituality are mainly due to unstable mind which alone keeps away our effort/desire of moving along spiritualism. In order to keep our mind or say concentration, the Guru’s Grace (Krupa) is ardently needed. When Guru is pleased there would be no hindrance and the Guru leads the disciple entirely on to the path of Spiritualism.
On this day, all spiritual aspirants and disciples perform ‘puja’ of their respective spiritual preceptor or ‘Gurudevs’.
The Spiritual aspirants and disciples knows that the Guru is the only guarantee for the individual to transcend the bondage of sorrow and death, and experience the Consciousness of the Reality.”
The relation of Guru-Sishya is as pious as that of Bhagavan–Devotee.
The Guru’s form should be meditated upon; the feet of the Guru should be worshipped; his words are to be treated as a Sacred Mantra; His Grace ensures final Liberation”.
The form of Guru is the root of Meditation,
The feet of Guru are the root of Worship,
The teachings of Guru is the root of all Hymns,
The Grace of Guru is the root of Salvation.
