sūtra, to stregnthen the students's understanding.
Performing the duties of āśrama-dharma are also helpful in purifying the heart
and understanding the transcendental reality. How the āśrama duties of the
brāhmaṇa help in this regard is described in the following statement of Bṛhad-
āraṇyaka Upaniṣad (4.4.22):
tam etaṁ vedānuvacanena brāhmaṇā vividiṣanti yajñena dānena tapasānāśanena
"By Vedic study, sacrifice, charity, austerity, and fasting, the brāhmaṇas strive to
understand the Supreme Personality of Godhead."
The usefulness of the brahminical duties such as truthfulness, austerity, and
mantra chanting is described in the following scriptural statements:
satyena labhayas tapasā hy eṣa ātmā samyak jñānena brahmacaryeṇa nityam
"By constant truthfulness, austerity, transcendental knowledge, and austerity,
one becomes eligible to associate with the Supreme Personality of Godhead."
—Muṇḍaka Upaniṣad 3.1.5
japyenaiva ca saṁsiddhyad
brāhmaṇā nātra saṁśayaḥ
kuryād anyan na vā kuryān
maitro brāhmaṇa ucyate
"Whether he performs other rituals and duties or not, one who perfectly chants
mantras glorifying the Supreme Personality of Godhead should be considered a
perfect brāhmaṇa, eligible to understand the Supreme Lord."
—Manu-saṁhitā 2.87
Association with those who understand the truth also brings one
transcendental knowledge. By this association Nārada and many other spiritual
aspirants attained interest to ask about spiritual life and were finally eligible to see
the Supreme Personality of Godhead face-to-face. Sanat-kumāra and many other
great sages have also helped many devotees by giving their association in this way.
The great value of contact with a self-realized soul is described in the following
statement of Bhagavad-gītā (4.34):
tad viddhi praṇipātena
paripraśnena sevayā
upadekṣyanti te jñānaṁ
