Sutra 21 tivra-samveganam asannah

Such enthusiastic and dedicated practices will increase the passion and strength of one's overall practice providing the fuel for its fruition. Samadhi is most close at hand and reachable (asannah) to those whose passion (samveganam) for it is the most intense (tivra) for they are less likely to be dissuaded from it. Those remain centered in their core energy and claim their natural position in the greater scheme of things (purusha). They find success, grace, and poise in the greater integrity of All Our Relations which is always near at hand. The presence of primordial wisdom may be unnoticed, ignored, barely noticed, or strong. As non-dual wisdom is increased, our practice becomes more focused and intense. Similarly when our practice becomes more onepointed and intense, closer at hand is samadhi.
