There are many festivals throughout the year dedicated to different spiritual forces, because man has always felt a sense of incompleteness within himself. He went in search of God, samadhi, emancipation because he wanted to project himself beyond the frontiers of finiteness. He wanted to expand his soul beyond the boundaries of time and space.
There is a junction point in life where both sides meet- the transcendental and the empirical. One is the dimension of time, space, object and limitation, and the other is the dimension of timelessness and it is transcendental. Guru stands exactly at the point where these dimensions meet. Therefore, in a guru you can always find the aspects of both creation and reality. He is finite and at the same time he is a replica of infinite.
The discovery of guru is a very ancient discovery. From that time, different gurus in different periods have emphasized the need for a guru in one’s life so that one may have spiritual support. On the day of Guru Purnima, the spiritual powers and grace of all gurus descends to this earthly plane in order to inspire the spiritually hungry souls and pilgrims towards the spiritual life.
Guru is always aware of his disciples and of their aspirations. For spiritual wellbeing and evolution, guru prefers to remain in an interim space after death, and once every year he comes down with his spiritual vibration taking care of his disciples, inspiring, energizing and increasing them. This is that day.
