Forms for Meditation

“Even if one concentrates his mind on the boar form of the Lord, that is also yoga. As confirmed in Bhagavad-gita, one who concentrates his mind constantly in meditation upon the Personality of Godhead in one of His many varieties of forms is the first-class yogi, and he can very easily attain trance simply by meditating upon the form of the Lord. If one is able to continue such meditation on the Lord's form at the time of one's death, one is liberated from this mortal body and is transferred to the kingdom of God.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.19.28 Purport)
