my parents are against me chanting, going to temple regularly.I wish to start chanting at least min 2 rounds,i cannot do that at home so can I chant outside when I go to Coll in some park? Is it not disrespecting my parents?

Please, try to be polite with Your parents. Help them in their daily works like cooking, washing etc.

Then at least on Sundays attend Temple Program. Chanting You can do in Your room when they sleep. For example early in the morning. As i know non Devotee Indians usually wake up after 6 AM. So in this way You can wake up nearly at 4:30 or 5 AM and chant.

In the park also You can chant, very good idea. But these days parks are crowded and very noisy in this way think Yourself what is better for You.

In order to wake up early You have to go to sleep early.

We sleep at 8 - 9 PM.
