Also, i am due to go to a Mahashi insight retreat in the summer so could you offer any advice on preperation before i go as in any meditation tips as to ensure i get the best from my time there.
Thankyou
Do you mean Mahasi above. If that is the case, you should work on your noting practice instead.

Mahasi centers do not teach Jhana. The teacher will likely ask you temporary put aside your Jhana practice, revert to the noting practice and report your experience accordingly.
