It is in vain to waste one’s time considering which God to worship. Worship Him in any form. It is the sincerity of devotion that matters.
Worship your chosen ideal with constant thought, repetition of holy names and meditation.
Give up pride and egotism and devoutly immerse yourself in the thought of God. Love without faith and sincerity is naught.
The first and foremost means of God realization is Love – love of the Lord all unsurpassed. Love of God purifies the mind and easily leads to mental concentration.
