the second Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha. For each of these, there are three forms; therefore there are twelve forms altogether. These twelve forms constitute the predominant names for the twelve months of the year as well as the twelve  tilaka  marks on the body. Each of the four Personalities of God-head expands into two other forms; thus there are eight forms, such as Puruṣottama, Acyuta, etc. The four forms (Vāsudeva, etc.), the twelve (Keśava, etc.), and the eight (Puruṣottama, etc.) all together constitute twenty-four forms. All the forms are differently named in accordance with the weapons They hold in Their four hands.
