Once upon a time there was sage living in his ashram. One morning, while he was offering his prayers to the Sun god, a small mouse fell in his hands from the sky. It was being carried by an eagle and badly wounded. The sage felt pity on the mouse and transformed it into a human girl to protect it from the eagle. He took the girl to his ashram and nurtured her as his own daughter. The daughter grew up in the ashram and attained ripe age for marriage.
The sage wanted to marry his daughter to the most powerful person in the world. When the sage thought about the potential bridegrooms, he realized that the Sun is the most powerful in the whole visible world around us. So, he asked his daughter, "Dear, I want you to marry the most powerful person in the world. And I see that the Sun is the most powerful in the whole world. Are you willing to marry the Sun god?" The daughter replied, "You are right father, but a small cloud could obstruct the power of the mighty Sun. Isn’t the cloud more powerful?" The sage replied, “OK, so will you marry the cloud god?” “But father, when the wind blows it could easily scatter away the thickest of the clouds. Isn’t the wind more powerful than the clouds?”
The sage asked again, “so, you want to marry the wind god?” “No father. Please think about it. Even the most powerful winds are blocked by a mountain. Isn’t the mountain mightier than the wind?” reasoned the daughter. “So, how about you marry the mountain god?” “Don’t rush father! I agree a mountain is mighty. But a small mouse can easily dig a tunnel through the mountain. Isn’t the mouse the most powerful creature in the whole world?” The disappointed sage said, “My child, I transformed your body from that of a mouse to a human and raised you for so many years in my ashram, but I couldn’t transform your mind. You better be a mouse and live your own life,” and transformed her back into a mouse.
Similarly a Guru offers protection to the disciples in distress and raises them as his own children. A Guru’s one and only desire is to liberate the disciples from the shackles of illusion and make them attain the ultimate peace and bliss that he constantly experiences. But we, the disciples fail to follow his directions and instead desire and seek the most mundane pleasures. We pester the Gurus for things like promotions, marriages, children, wealth, health etc. while they seek to liberate us from this whole cycle of birth, death and rebirth. It doesn’t matter if we live in an ashram, dress like devotees and perform all the religious rituals. As long as our mind does not transform and progress on the path shown by the Guru, there is no use of the bodily transformations.
