[If] one says, “I will not go before the Ark in colored clothing,” he may not even go in white clothing. [If he says], “I will not go [before the Ark] in sandals,” he may not even go barefoot.  One who makes his tefillin round endangers himself and does not fulfill the precept. [If] he places [the tefillin] on his forehead, or in his palm, it is the manner of heresy. [If] he covered them with gold, or [if] he placed it on his sleeve, this is considered the way of the outsiders.
