I am a Hindu and have been associated with Vipassana for about 15 years now (U Ba Khin / Goenkaji's tradition). I dont think there is any contradiction there. Infect you may end up understanding Dhamma / Gita much better. Dont think go for it, post Vipassana you might actually understand the true meaning of several Kabir Dohas and so on so forth.
What may go down is your faith on certain rituals which you may come to realise were started by brahmins/ other sections of society for their personal monetary gain and do not have much to do with Dhamma.
For 10 days please just honour the following:
1. Noble Silence - most important
2. try to work on mindfulness to the maximum and follow instructions with zest
The gain you can get cannot be measured.
