गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

In these words the amorous pastimes of the Lord are described. The word "a-
kāmena" here means "with something that bears certainly similarities to lust". This
thing with some similarities to material lust is the Lord's pure spiritual love. That
is the meaning. With spiritual love He enjoys the goddess of fortune, who is
actually Himself. In this way He finds pleasure and fulfillment. For this there is no
fault on His part. By touching the goddess of fortune, who is actually Himself, the
Lord enjoys transcendental bliss. It is like a person gazing at his own
handsomeness (in a mirror). That is what is said here.
Different from His spiritual potency (parā śakti) is the potency of the Lord's
form (svarūpa-śakti). The Śruti-śāstras and other scriptures explain that through
the svarūpa-śakti the Supreme Lord manifests as the best of males, and through
the parā śakti the Lord manifests His various transcendental qualities. It is through
the parā śakti that the Lord manifests His knowledge, bliss, mercy, opulence,
power, sweetness, and other qualities.
It is also through the parā śakti that the Vedic scriptures are manifested. In the
same way is manifested the earth and other places. manifesting as the Lord's
pleasure potency (hlādinī śakti), the parā śakti appears as Śrī Rādhā, the jewel of
teenage girls.
Although the Lord and His parā śakti are not different, still, for enjoying
different pastimes, They are manifested as different. In this way the Lord's desires
are perfectly and completely fulfilled.
These manifestations of the parā śakti, beginning with the manifestation of the
Lord's qualities, are not manifested only recently. They are beginningless and
eternal. They will never cease to exist. Therefore the devotees should meditate on
the Supreme Personality of Godhead as accompanied by the goddess of fortune.

The Many Forms of the Supreme Personality of Godhead
Introduction by Śrīla Baladeva Vidyābhūṣaṇa
In the Gopāla-tāpanī Upaniṣad (1.54) it is said:
tasmāt eva kṛṣṇaḥ paro devas taṁ dhyāyet taṁ raset taṁ bhajet taṁ yajet. iti. oṁ
tat sat.
"Therefore, Lord Kṛṣṇa is the Supreme Personality of Godhead. One should
meditate on Him, glorify Him, serve Him, and worship Him. Oṁ Tat Sat."
