If he cannot do that either, he must meditate upon Bhagavat Vâsudeva (Vishnu), who is adorned with a diadem, with ear-rings, and with bracelets, who has the (mystic mark) Srîvatsa and a garland of wood-flowers on his breast, whose aspect is pleasing, who has four arms, who holds the shell, the discus, the mace, and the lotus-flower, and whose feet are supported (and worshipped) by the earth.
