I did learn the basics of meditation through late Master Hằng Hiển [the previous head monk of her temple]. He taught me to sit in full lotus and use the breath counting technique.
Thank you for your inquiry.
Yes you certainly may and should.
We will be teaching the secret techniques of the Chan patriarchs at our meditation class; we would certainly be glad to teach you as much as you can absorb.
In the future, if there is interest, we would consider organizing a one-day Chan class at your local temple too.
