There is no harm in concentrating sometimes in the heart and sometimes above the head. But concentration in either place does not mean keeping the attention fixed on a particular spot; you have to take your station of consciousness in either place and concentrate there not on the place, but on the Divine. This can be done with eyes shut or with eyes open, according as it best suits you.
You can concentrate on the sun, but to concentrate on the Divine is better than to concentrate on the sun.
