Dear Students,
As you are proceeding for Deepawali Vacations, you are looking forward to free time, fun and
frolic with family and friends. I, on the behalf of my department, wish you all the joy and
happiness in this festival period.
Deepawali is a festival of lights. We lighten lamps to drive away the darkness of moonless
night of Deepawali. Do not forget, it is also a very crucial period for you when you can pull out
some time for your revision. Devote your mornings and afternoons to academics (self-study)
while evening should be reserved for pure enjoyment. Do not plan any study in evening
duration, just enjoy freely and have a good time if you have studied properly in the morning.
As you lighten the lamps of Deepawali, also lighten the lamp of knowledge in your heart. I am
offering you unlighted deepaks in the form of Chemistry problems. Lighten them with the fire
of your mind, and solve them all to celebrate true deepawali.
May your interest in your subject intensify. May you learn to work hard with consistency. May
you always maintain your focus. May you be true to yourself. May Ma Saraswati bless you
with all that is desirable. This is a blessing from my heart.
With affection,
Shishir Mittal,
VP(SW) and HoD (Chemistry),
Resonance.
