In the Vedas, God is referred by many names Brahman, Bhagwan,
Deva,
Paramātmā,
Praṇa,
Puruṣh, Sat,
etc. In some places, while referring to His formless aspect, God is said to be
Akshar,
which means imperishable. The Bṛihadāraṇyak Upaniṣhad states
etasya vā akṣharasya praśhāsane gārgi
sūryāchandramasau vidhṛitau tiṣhṭhataḥ
(3.8.9)
“Under the mighty control of the Imperishable, the sun and the moon are held on their course.”
Shree Krishna mentions in this verse the word
sangraheṇa,
which means “in brief.” He says that this path is very difficult to follow and not suitable for everyone. Therefore, He will not elaborate much and briefly describe this path of
yog-miśhrā
bhakti;
that leads to attaining the formless aspect of God. It demands living a life of rigid continence and perform severe austerities. Renouncing worldly desires and practicing
brahmacharya,
a vow of celibacy. As was previously detailed in verse 6.14, the practice of celibacy conserves a person’s physical energy. This energy, when channelized through sadhana, gets transformed into spiritual energy. It also enhances the intellect and memory power of the
sādhaks
(spiritual aspirants)
and helps them comprehend the spiritual subjects better.
