Reason as also persistence are of three kinds according to the qualities; hear them related, unreservedly and severally, O Dhananjaya.
Gītā 18·29The reason armed with the intelligent will works in man in whatever manner or measure he may possess these human gifts and it is accordingly right or perverted, clouded or luminous, narrow and small or large and wide like the mind of its possessor. It is the understanding power of his nature, buddhi, that chooses the work for him or, more often, approves and sets its sanction on one or other among the many suggestions of his complex instincts, impulsions, ideas and desires. It is that which determines for him what is right or wrong, to be done or not to be done, Dharma or Adharma. And the persistence of the will is that continuous force of mental Nature which sustains the work and gives it consistence and persistence. Here again there is the incidence of the gunas.
