Next, offer ball-food to present to the iṣṭadevatā, and also perform the rite of taking food as one wishes. If there are leftovers, set aside another portion to relieve the hungry, impoverished, and begging. One should give rise to this thought: 'It is to sustain the vessel of this body in peace and practice the path that I receive this morsel food, just as one oils an axle to keep it from breaking and wear so as to reach one's destination, and not for the sake of fine flavors.' Without increasing or decreasing one's mind [in craving or aversion] or generating thoughts of pleasing the flesh and adorning the body, one then visualises the dharmadhātu-hṛdaya syllable purifying all the food throughout, and with the karmavajra empowers one's own body.
