“A Guru should never sell mantra-knowledge to a disciple. A Guru who sells mantra is sinful and surely goes to hell.

Mantra-dīkṣā is to be given only through generosity and grace. One whose mind is tainted by greed is not a Guru and cannot uplift a disciple.

Whoever gives dīkṣā out of desire for wealth takes the wrong path. For such a person, no siddhi of the mantra arises; the practice becomes fruitless.”

Kulārṇava Tantra 13.108–110
