The Instruction of Bala and Atibala
कामं बहुगुणास्सर्वे त्वय्येते नात्र संशय:।
तपसा सम्भृते चैते बहुरूपे भविष्यत:।।1.22.19।।
kāmaṃ bahuguṇāḥ sarve tvayy ete nātra saṃśayaḥ | tapasā sambhṛte caitē bahurūpe bhaviṣyataḥ || 1.22.19 ||
Indeed, all these many virtues are found in you—there is no doubt. And when these two sciences are strengthened through austerity (tapas), they will manifest in many forms to serve you.
You possess all these qualities in great measure. There is no doubt that If these two sciences (mantras) are nourished with austerities they will assume multiple forms (and benefit you)".
Dharma is sustained by tapas (discipline). Power and knowledge become truly effective—and ethically directed—when cultivated through self-restraint and spiritual effort rather than indulgence.
Viśvāmitra reassures Rāma of his innate virtues and explains that the mantra-vidyās grow more versatile when supported by austerity.
Inner discipline and receptivity: Rāma is portrayed as already virtuous, and capable of deepening that virtue through tapas.
