The Lord appears in the particular form loved by a particular type of devotee. There are millions of forms of the Lord, but they are one Absolute. As stated in the Brahma-samhita, advaitam acyutam anadim ananta-rupam: [Bs 5.33] all the different forms of the Lord are one, but some devotees want to see Him in the form of Radha and Krsna, others prefer Him as Sita and Ramacandra, others would see Him as Laksmi-Narayana, and others want to see Him as four-handed Narayana, Vasudeva. The Lord has innumerable forms, and He appears in a particular form as preferred by a particular type of devotee. A yogi is advised to meditate upon the forms that are approved by devotees. A yogi cannot imagine a form for meditation. Those so-called yogis who manufacture a circle or target are engaged in nonsense. Actually, a yogi must meditate upon the form of the Supreme Personality of Godhead that has been experienced by the Lords pure devotees. Yogi means devotee. Yogis who are not actually pure devotees should follow in the footsteps of devotees. It is especially mentioned here that the yogi should meditate upon the form which is thus approved; he cannot manufacture a form of the Lord.
