Sings Bhagavad Gita:

तमेव शरणं गच्छ सर्वभावेन भारत।
तत्प्रसादात्परां शान्तिं स्थानं प्राप्स्यसि शाश्वतम्॥१८-६२॥

tameva śaraṇaṁ gaccha sarvabhāvena bhārata|
tatprasādātparāṁ śāntiṁ sthānaṁ prāpsyasi śāśvatam||18-62||

“Seek refuge with all your heart, O Bharat, in that God by whose grace you will attain to repose and the everlasting, ultimate bliss.’’

So if we have to meditate, we should do it within the realm of the heart.The heart is the true abode of God. Although God is all-pervading, he is realized only by meditation in the realm of heart.

Humble Wishes!!!
