Text 26] The Supreme Lord Is Equal to Everyone
35
tān aham dviṣataḥ krūrān 
    saṁsāreṣu narādhamān 
    kṣipāmy ajasram aśubhān 
    āsurīṣv eva yoniṣu
There are many such injunctions. One should not try to worship Kṛṣṇa unfavorably; otherwise he must be punished, at least for one life, to be purified. As one should not try to be killed by embracing an enemy, a tiger or a snake, one should not blaspheme the Supreme Personality of Godhead and become His enemy in order to be put into hellish life.

Śrīla Madhvācārya also says in many ways that one should not blaspheme Lord Viṣṇu through one's mind, words or actions, for a blasphemer will go to hellish life along with his forefathers.

    majjanti pitaras tasya

In  Bhagavad-gītā  (16.19–20) the Lord says:
tān aham dviṣataḥ krūrān 
    saṁsāreṣu narādhamān 
    kṣipāmy ajasram aśubhān 
    āsurīṣv eva yoniṣu
āsurīṁ yonim āpannā 
    mūḍhā janmani janmani 
    mām aprāpyaiva kaunteya 
    tato yānty adhamāṁ gatim
“Those who are envious and mischievous, who are the lowest among men, are cast by Me into the ocean of material existence, into various demoniac species of life. Attaining repeated birth amongst the species of demoniac life, such persons can never approach Me. Gradually they sink
