The KulÃ¡rnava Tantra teaches that:Â
â€œThe Guru must relinquish taking as a disciple someone elseâ€™s disciple, one who incites the others, one who is inclined towards the forbidden and to omit what is recommended, one who divulges secrets, one who strives to find faults in others, one who is ungrateful, treacherous, disloyal to the Master, one who is always demanding, one who is deceitful, who is proud, who believes to be better than everyone else, the insincere, with erroneus reasoning, who likes to quarrel, to refute the others without reason, the untrustworthy, who speaks badly on the back of the others, one who speaks like a brahman despite having no such knowledge, the plagiarist, condemned by all, who is hard, who betrays the Master, who fools himself, who incites to falsities, prone to jealousy, intoxication (by drugs), selfishness, of jealous choleric and hard mind, unstable, creator of confusion, without peace or correct conduct, who mocks the words of the Master, one who is cursed by a Guru, those are the ones to rejectâ€.
The KulÃ¡rnava Tantra also cites the qualities:
â€œThe chosen disciple should be gifted with good qualities. He must be someone trustworthy, not intoxicated (by drugs), obliging, not prone to attack the others, with aversion to hear praises to himself, owever, genial towards criticism, it must be someone who speaks of the Guru, always in the proximity of the Guru, pleasant to the Guru, constantly ocupied in his service, with mind, words and body; one who carries out the orders of the Guru, who disseminates the glories of the Guru, aware of the authority of the word of the Guru; who follows the intentions of the Guru; who acts at the service of the Guru; without pride of social class, honour of wealth in the presence of the Guru; who does not covet the belongings of the Guruâ€.
The reader must have observed that the Hindu cripture insisted in certain disciplinary questions. And, for the record, it is a tantric shÃ¡stra, Tantra being a libertarian philosophy. Imagine, then, the demands of the brahmachÃ¡rya line, that is restrictive!Â Â
Freedom is our most precious good.
When confronting freedom with discipline,
if the latter forces the former, choose freedom.
